Description

[0001]
BACKGROUND OF THE INVENTION
The present invention provides a correction function for converting a character code conversion device and a recording medium required between systems having different character code systems into a character code that is a conversion error in a predetermined code conversion table. The present invention relates to a character code conversion device possessed.
[0002]
[Prior art]
Conventionally, when an undefined character code is found in the code conversion table, the character code conversion device has taken measures to output it with a substitute character or to interrupt the conversion process.
[0003]
Also, most of the characters that cause conversion errors are undefined characters on the code conversion table of user-defined characters and non-JIS extended characters, and usually need to be converted to arbitrary characters in the conversion destination system.
[0004]
For this reason, with the configuration as shown in FIG. 10, the user investigates the character that causes the conversion error before executing the conversion process, and corrects the input data or the code conversion table in advance. In order to investigate the presence of undefined characters, it is necessary to create and execute a manual or investigation program.
[0005]
FIG. 10 is an explanatory diagram of the prior art.
In FIG. 10, input data 41 is character code data to be converted.
[0006]
The investigation program 42 is a program for investigating whether the input data 41 includes a character code that causes a conversion error.
The investigation result list 43 is a list of results obtained by investigating the character codes that cause the conversion error by reading the input data 41 by the investigation program 42 and their positions.
[0007]
The table correction 44 refers to the investigation result list 43 and corrects the code conversion table 45 for the character code having a conversion error.
The code conversion table 45 is a table for converting input data.
[0008]
The character code conversion device 46 converts the input data 41 into a conversion destination code using the corrected code conversion table 45 and stores it as output data 47.
[0009]
The output data 47 is converted character code data.
Next, the operation will be briefly described.
(1) The investigation program 42 refers to the code conversion table 45 for the input data 41, investigates the character code causing the conversion error, and its position, and outputs the investigation result list 43.
[0010]
(2) The table correction 44 corrects the code conversion table 45 by, for example, registering a conversion destination character code for a character code that causes a conversion error based on the investigation result list 43.
[0011]
(3) The character code conversion device 46 converts the input data 41 into a conversion destination character code using the corrected code conversion table 45 and stores it as output data 47.
[0012]
[Problems to be solved by the invention]
As described above, there has been a problem that the investigation of undefined characters is very time-consuming and inefficient. In addition, since the search program searches for conversion error characters from the entire input data, if the amount of data is large, a search, conversion, and two readings are required, and there is a problem that processing time is required.
[0013]
In order to solve these problems, the present invention performs conversion by referring to a code conversion table for input data, and in the case of an undefined code, outputs it as a substitute character and stores the character code and position in the table. For the purpose of realizing the conversion to the specified character code and the conversion to the code conversion table, quickly realizing the conversion of the character code by reading the character data once, and automatically reflecting it to the next code conversion. Yes.
[0014]
[Means for Solving the Problems]
Means for solving the problem will be described with reference to FIG.
In FIG. 1, a character code conversion means 2 refers to a code conversion table 4 and converts a character code in input data 1.
[0015]
The conversion error accumulating unit 3 replaces the substitute character code when a conversion error occurs, and accumulates the original character code and its position information in the conversion error history table 5.
[0016]
The output data 6 is a character code after conversion.
The conversion error correction means 7 displays the contents of the conversion error history table 5 on the display / input device 8 and replaces (corrects) the substitute characters with correct characters in response to the error treatment input.
[0017]
The error treatment reusing means 9 reflects the substitute character in the code conversion table 4 when the substitute character is replaced with the correct character (registers the correct character code in association with the original character code).
[0018]
Next, the operation will be described.
The character code extracted from the input data 1 by the character code conversion means 2 is converted into another character code with reference to the code conversion table 4 and output, and the conversion error storage means 3 has a conversion error due to an undefined code. Sometimes the substitute code is output and the original character code and the output position are accumulated in the conversion error history table 5, and the conversion error correction means 7 displays the converted character code character and the substitute character, and also in the conversion error history table 5. The stored original character code and output position information are displayed.
[0019]
At this time, in response to the input of the character code output by the conversion error correction means 7 for the original character code displayed on the display / input device 8, the substitute character is replaced with the character of the character code. .
[0020]
In addition, when the conversion error correction means 7 inputs a character to be output for the original character code displayed on the display / input device 8, the substitute character is replaced with the character.
[0021]
Further, the error treatment reuse means 9 registers the character code of the character with the substitute character replaced in association with the original character code in the code conversion table 4 and uses it next time.
[0022]
Therefore, the input data 1 is converted by referring to the code conversion table 4, and if it is an undefined code, it is output as a substitute character, and the character code and position are stored in the conversion error history table 5. By replacing the character code or character specified based on the character code and reflecting it in the code conversion table 4, the character code can be quickly converted by one reading of the character data and automatically reflected in the subsequent processing. It becomes possible.
[0023]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments and operations of the present invention will be described in detail sequentially with reference to FIGS. Here, a program read from a recording medium, a program read from a hard disk device or the like as an external storage device, or a program read from a center external storage device and transferred via a line is loaded into the main memory and started. Various processes described below are performed.
[0024]
Here, the operation of the configuration of FIG. 1 will be described with reference to FIGS. 2 and 3.
FIG. 2 is a diagram for explaining the operation of the present invention (part 1).
(1) The character code conversion means 2 reads the input data 1 as in S1, refers to the code conversion table 4, converts the character code, and outputs it as output data 6 as shown in S4.
[0025]
(2) When there is an undefined code in the read input data 1 at the time of conversion of the character code of (1), the conversion error accumulation means 3 shows the undefined code in the conversion error history table 5 as shown in FIG. Information on the code value, the number of occurrences, and the output position (line-digit) is accumulated, and a substitute character (substitute character code) is output as output data 6.
[0026]
According to the above (1) and (2), as shown in the figure, the character (character code) after code conversion and the undefined code are output as alternative characters (alternative character code) as output data 6, and a conversion error occurs. The history table 5 stores information on the code value, the number of occurrences, and the output position (line-digit) of the original character of the substitute character (substitute character code).
[0027]
FIG. 3 is a diagram for explaining the operation of the present invention (part 2).
(3) Based on the conversion error history table 5 accumulated in (2), the display / input device 8 displays the conversion source code, the number of occurrences, and the conversion destination code, as shown in the figure, and any entry to the operator. Is selected to prompt input of a conversion destination code (S11, S12).
[0028]
(4) In response to prompting the input of the conversion destination code in (3), when the operator inputs the character code converted into the conversion destination code column on the display / input device 8, the conversion error correction means 7 As shown in S13, a new association table in which the conversion source code and the conversion destination code are associated is created, and the substitute character in the output data is replaced with the character of the conversion destination code based on the new association table. Then, the output data 6 shown in FIG.
[0029]
With respect to the alternative characters in the output data 6 according to the above (3) and (4), the columns of the conversion source code, the number of occurrences and the conversion destination code stored in the conversion error history table 5 are displayed on the display / input device 8 In response to the input of the conversion destination code, the substitute character in the output data 6 can be automatically replaced with the character of the conversion destination code.
[0030]
Next, according to the order shown in the flowchart of FIG. 4, a procedure for outputting an alternative character to the output data 6 of the configuration of FIG. 1 and registering the conversion source code value, the number of occurrences, and the output position in the conversion error history table 5 is described. This will be described in detail.

FIG. 4 is a flowchart for explaining the operation of the present invention (part 1).
In FIG. 4, S21 reads input data. This reads the input data 1 as shown in S1 of FIG.
[0032]
S22 takes out one character at a time.
In S23, the code conversion table is searched. This searches the code conversion table 4 and searches for the character code of the conversion destination with respect to the character code of the conversion source.
[0033]
In step S24, it is determined whether the code conversion table 4 exists. In the case of YES, the data is converted in S30 and output as output data 6, and the process proceeds to S31. On the other hand, in the case of NO, since it is found that the code is undefined, S25 to S29 are executed.
[0034]
In S25, the conversion error history table 5 is searched. This is done by searching the conversion error history table 5 of FIG. 2 described above to determine whether the same undefined code has been registered before. In the case of YES, since it is found that it is already registered in the conversion error history table 5, the number of occurrences of the corresponding code value entry in the conversion error history table 5 is updated in S27, and the output position (row-digit) is updated. Add and proceed to S29. On the other hand, in the case of NO in S25, it is found that it is not registered in the conversion error history table 5, so in S28, it is newly registered in the conversion error history table 5, and the original code (code value), the number of occurrences, the output position ( Line-digit) is registered, and the process proceeds to S29.
[0035]
In step S29, an alternative character is output. As shown in the output data 6 of FIG. 2 described above, an alternative character (here, ■) is output for the undefined code.
In S31, it is determined whether the input data is over. In the case of YES, since the process has been completed for all input data 1, the process ends (END). In the case of NO, the process returns to S22 and the next one character is extracted and repeated.
[0036]
As described above, the input data 1 is read and code conversion is performed by referring to the code conversion table 4 character by character. When an undefined code appears at this time, the code value, the number of occurrences, and the output position are displayed in the conversion error history table 5. By registering (line-digit) and outputting an alternative character, even if there is an undefined code, output data 6 is output with the alternative character, and the conversion source code value, the number of occurrences, and the output position are converted error history It can be stored in the table 5.
[0037]
Next, in accordance with the order shown in the flowchart of FIG. 5, the procedure for replacing the substitute character in the output data 6 with the correct character (character code) based on the conversion error history table 5 of the configuration of FIG. 1 will be described in detail. To do.

S44 is selected.
In S45, the conversion destination code is input. In S44 and S45, the operator selects one of the entries on the error list in the window 1 on the right side of FIG. 8 displayed in S43, and inputs the correct code of the conversion destination by key input.
[0041]
In S46, it is confirmed whether the operator is correct. If OK, the process proceeds to S47. In the case of NG, the process returns to S44 and is repeated.
In S47, the conversion error history table 5 is updated. This updates the correct conversion destination code input by the operator in the conversion error history table 5 shown in FIG.
[0042]
In S48, it is determined whether the correction request is over. If YES, the process proceeds to S49. If NO, return to S42 and repeat.
In S49, a replacement request is made. This is because the conversion error history table 5 has been updated, and this is collectively requested to replace the substitute characters in the output data 6 with correct characters (character codes).
[0043]
In S50, the conversion error history table 5 is read.
In step S51, output positions are sequentially extracted.
S52 replaces the substitute character in the output data 6 with the conversion destination code based on the output position.
[0044]
S53 determines whether the history is over. If YES, the process ends (END). If NO, return to S51 and repeat.
As described above, the output data 6 including the substitute character and the contents of the conversion error history table 5 are respectively displayed as shown in window 2 and window 1 of FIG. 8 to be described later, and an arbitrary entry displaying the contents of the conversion error history table 5 is displayed. When the correct conversion destination code is input, the corresponding substitute character in the output data 6 can be automatically replaced with the correct conversion destination character (character code).

-Conversion source code:
-Conversion destination code:
The correct character after the conversion is input in the conversion destination code column in the column of (2), and the alternative character on the window 2 may be overwritten with the correct character.
[0050]
In S68, it is determined whether there is another same conversion source code. In response to the input of the correct converted character in S67, it is determined whether there is another conversion source code. If YES, all the same conversion source codes in the output data 6 on the window 2 are replaced with correct conversion characters in S69, and the process proceeds to S70. On the other hand, in the case of NO in S68, the process proceeds to S70.
[0051]
In S70, the input conversion destination character is reflected in the conversion destination code of the window 1.
S71 is positioned as the next substitute character on the window 2.
S72 determines whether the substitute character ends. If YES, the process proceeds to S73. If NO, return to S67 and repeat.
[0052]
S73 confirms. If OK, the process proceeds to S74. In the case of NG, the process returns to S66 and is repeated.
In S74, the output data is updated.
[0053]
In S75, the conversion error history table 5 is updated.
As described above, the contents of the output data 6 including the substitute characters and the contents of the conversion error history table 5 are respectively displayed as shown in window 1 and window 2 of FIG. 9 to be described later, and displayed on window 2 (or on the error correction input window on the lower right). ), It is possible to automatically replace the corresponding substitute character in the output data 6 with the correct conversion destination character (character code).
[0054]
Next, the procedure for reflecting the contents of the conversion error history table 5 having the configuration shown in FIG. 1 in the code conversion table 4 will be described in detail according to the order shown in the flowchart of FIG.
[0055]
FIG. 7 is a diagram for explaining the operation of the present invention (part 4).
FIG. 7A shows a flowchart.
In FIG. 7A, S81 requests reuse.
[0056]

In step S83, conversion destination codes are sequentially extracted.
In S84, addition to the code conversion table 4 is performed. Add
-Conversion source code:
-Conversion destination code:
Are added to the code conversion table 4 as a pair.
[0057]
In S85, it is determined whether the history is over. If YES, the process ends (END). If NO, return to S83 and repeat.
As described above, an undefined conversion destination code registered in the conversion error history table 5 can be added to the code conversion table 4 by pairing the conversion source code and the correct conversion destination code.
[0058]
FIG. 7B shows a state where the code is added to the code conversion table 4. Here, the above-described new association table of FIG. 3 is created from the conversion error history table 5, and the conversion source code and the correct conversion destination code in this are paired and added to the code conversion table 4.
[0059]
As described above, the undefined code is automatically added to the code conversion table 4, and the code conversion is automatically performed after the next time.
FIG. 8 shows a display example (part 1) of the present invention. This is because the output data 6 is displayed in the left window 2 (alternate characters are indicated by ■), and the content of the conversion error history table 5 (conversion source code, conversion destination code, number of occurrences, output position) in the right window 1 Is displayed. In this case, when the operator inputs the conversion destination code, it is automatically registered as the conversion destination code, and the corresponding substitute character in the output data 6 is automatically replaced with the character corresponding to the correct conversion destination code and displayed. .
[0060]
FIG. 9 shows a display example (No. 2) of the present invention. This is because the output data 6 is displayed in the left window 2 (alternate characters are indicated by ■), and the content of the conversion error history table 5 (conversion source code, conversion destination code, number of occurrences, output position) in the right window 1 Is displayed in the lower right error correction input window by inputting the correct characters (and displaying the character code) as the output position, conversion source code, and conversion destination code. In this case, when the operator inputs a key for the conversion destination, it is automatically registered as a conversion destination code, and the corresponding substitute character in the output data 6 is automatically replaced with the correct character (conversion destination code) and displayed. .
[0061]
As described above, the character code conversion according to the present invention is performed in real time at the same time that the correct character code is input for the undefined character code, and the positional information is stored for the undefined character code. It goes without saying that batch processing may be performed simultaneously with the input of the character code.
[0062]
【The invention's effect】
As described above, according to the present invention, the input data 1 is converted by referring to the code conversion table 4, and in the case of an undefined code, it is output as a substitute character and the character code is stored in the conversion error history table 5. Since the position is accumulated and replaced with the specified character code or character based on the conversion error history table 5 and reflected in the code conversion table 4, the character code is read by reading the character data once. The conversion can be realized quickly and can be automatically reflected in the subsequent processing. As a result, it is no longer necessary to investigate undefined codes in advance, and it is possible to have a high-quality undefined character investigation function through code conversion. In addition to the code conversion table 4, the code can be automatically converted from the next time.
[0063]
Furthermore, since the character strings before and after the undefined character code are displayed, the character string to be edited can be easily estimated from the context. Therefore, the user does not need to refer to the file before the change one by one.
[0064]
In addition, when undefined character codes are corrected, the undefined characters, that is, the characters to be corrected are sequentially searched and a screen prompting the correction is displayed, so that the user does not have to search for the characters to be edited. , Work burden on the user is reduced.
