Module:Unicode data/documentation

This module is used for accessing the Unicode character database (version 11.0), derived from files found in http://www.unicode.org/Public/UNIDATA/ .

Functions

All of these functions can only be used in a module. For template-invokable functions, see Module:Unicode data/templates.

lookup_name

Look up the name of a code point. Used by Module:character info, Module:character list, Module:Template:also, and Module:mul-domino def.

lookup_image

Look up the image for a codepoint. Used by Module:character info and Module:character list.

enum_blocks

Used in a for in loop in Module:character list to iterate through the array of block ranges.

lookup_plane

Returns the name of the plane to which a codepoint belongs. Unused.

get_block_range

Given a block name, returns the range of codepoints included in the block. Used by Module:character list.

is_valid_pagename

Given a string, returns true or false depending on whether the string can be used as a page title. Used by Module:template link.

add_dotted_circle

Given a string, places a dotted circle before every combining character in the string. Used by Module:category tree/charactercat and Module:grc-utilities.

char_to_script

Given a character or a codepoint, returns the Wiktionary script code for the character, or else "None", using Module:Unicode data/scripts. Used by Module:character info, Module:Template:also, Module:character list, and Module:games.

get_entry_title

Returns the title for the entry on a character, which is a subpage of Unsupported titles for characters that cannot appear in pagenames. See Manual:Page title on the MediaWiki website for more information. Used by Module:character info and Module:character list.

The following functions relate to a codepoint's General Category. They receive a codepoint and return two values: a boolean (which expresses whether the codepoint fulfills the condition) and a string describing the General Category, if the character is in the General Categories of Separator (Z) or Other (C), or the string "assigned". They use Module:Unicode data/control.

is_assigned

Checks whether a codepoint's General Category is not Cn (Other, unassigned). Used by Module:character list.

is_printable

Checks whether a codepoint is printable: that its General Category is not "Other" (C), "Separator, line" (Zl), or "Separator, paragraph" (Zp). Used by Module:character info and Module:character list.

is_whitespace

Checks whether a codepoint's General Category is Zs ("Separator, space"). Used by Module:character list and Module:links/print data.

User:Kephir/Unicode contains scripts which may be helpful in maintaining this database.

Data modules

The data used by functions in this module is found on subpages. Most of them were constructed by the scripts given in User:Kephir/Unicode

• Module:Unicode data/aliases: the formal name aliases for characters (from NameAliases.txt)
• Module:Unicode data/blocks: the list of Unicode blocks (from Blocks.txt); currently used by Module:Unicode data/sandbox
• Module:Unicode data/category: data mapping characters to their General Category (from DerivedGeneralCategory.txt)
• Module:Unicode data/control: data for identifying characters that belong to the General Categories of Separator and Other (from DerivedGeneralCategory.txt)
• Module:Unicode data/combining: data mapping characters to their Combining Classes (from DerivedCombiningClass.txt)
• Module:Unicode data/Hangul: data used to generate the names of Hangul syllables (from Jamo.txt); only used by Module:Unicode data/sandbox
• Module:Unicode data/scripts: data mapping characters to their Wiktionary script code (not the official Unicode script property), generated from Module:scripts/data by Module:User:Erutuon/script recognition.

The name and image data modules (Module:Unicode data/names/xxx and Module:Unicode data/images/xxx) were compiled from UnicodeData.txt. Each one contains, at maximum, code points U+xxx000 to U+xxxFFF.
