 - `--log.escape-control-chars`: this flag applies to the control characters, which have hex codes below `\x20`, 
   and also the character DEL with hex code `\x7f`. When the flag value is set to `false`, control 
-character will be retained, and its actual value will be displayed when it 
-is a visible character, or a space ` ` character will be displayed if it is 
-not a visible character. The same will happen to `DEL` character (code `\xF7`), 
-even though it is not a control character, because it is not visible. For example, 
-control characer `\n` is visible, so a `\n` will be displayed in the log, and 
-control character `BEL` is not visible, so a space ` ` would be displayed.
-When its value is set to true, the hex code for the character is displayed, for 
-example, `BEL` character would be displayed as its hex code, `\x07`.
