-- Combining character data used when categorising unusual characters. These resolve into two patterns, used to find
-- single combining characters (i.e. character + diacritic(s)) or double combining characters (i.e. character +
-- diacritic(s) + character).
-- Charsets are in the format used by Unicode's UnicodeSet tool: https://util.unicode.org/UnicodeJsps/list-unicodeset.jsp.
-- Single combining characters.
-- Charset: [[:M:]&[:^Canonical_Combining_Class=/^Double_/:]&[:^subhead=Grapheme joiner:]&[:^Variation_Selector=Yes:]]
-- Note: concatenating hundreds of lines at once gives an error, so () are used every 150 lines to break it up into chunks.

Given a pagename (or {nil} for the current page), create and return a data structure describing the page. The returned
object includes the following fields:
* `comb_chars`: A table containing various Lua character class patterns for different types of combined characters
(those that decompose into multiple characters in the NFD decomposition). The patterns are meant to be used with
{mw.ustring.find()}. The keys are:
** `single`: Single combining characters (character + diacritic), without surrounding brackets;
** `double`: Double combining characters (character + diacritic + character), without surrounding brackets;
** `vs`: Variation selectors, without surrounding brackets;
** `all`: Concatenation of `single` + `double` + `vs`, without surrounding brackets;
** `diacritics_single`: Like `single` but with surrounding brackets;
** `diacritics_double`: Like `double` but with surrounding brackets;
** `diacritics_all`: Like `all` but with surrounding brackets;
** `combined_single`: Lua pattern for matching a spacing character followed by one or more single combining characters;
** `combined_double`: Lua pattern for matching a combination of two spacing characters separated by one or more double
combining characters, possibly also with single combining characters;
* `emoji_pattern`: A Lua character class pattern (including surrounding brackets) that matches emojis. Meant to be used
with {mw.ustring.find()}.
* `L2_list`: Ordered list of L2 headings on the page, with the extra key `n` that gives the length of the list.
* `L2_sections`: Lookup table of L2 headings on the page, where the key is the section number assigned by the preprocessor, and the value is the L2 heading name. Once an invocation has got its actual section number from get_current_L2 in [[Module:pages]], it can use this table to determine its parent L2. TODO: We could expand this to include subsections, to check POS headings are correct etc.
* `unsupported_titles`: Map from pagenames to canonical titles for unsupported-title pages.
* `namespace`: Namespace of the pagename.
* `ns`: Namespace table for the page from mw.site.namespaces (TODO: merge with `namespace` above).
* `full_raw_pagename`: Full version of the '''RAW''' pagename (i.e. unsupported-title pages aren't canonicalized);
including the namespace and the root (portion before the slash).
* `pagename`: Canonicalized subpage portion of the pagename (unsupported-title pages are canonicalized).
* `decompose_pagename`: Equivalent of `pagename` in NFD decomposition.
* `pagename_len`: Length of `pagename` in Unicode chars, where combinations of spacing character + decomposed diacritic
are treated as single characters.
* `explode_pagename`: Set of characters found in `pagename`. The keys are characters (where combinations of spacing
character + decomposed diacritic are treated as single characters).
* `encoded_pagename`: FIXME: Document me.
* `pagename_defaultsort`: FIXME: Document me.
* `raw_defaultsort`: FIXME: Document me.
* `wikitext_topic_cat`: FIXME: Document me.
* `wikitext_langname_cat`: FIXME: Document me.
