Module:Unicode data/doc

This is a documentation subpage for Module:Unicode data (see that page for the module itself).
It contains usage information, categories and other content that is not part of the original module page.

Usage[edit]

This module provides functions that access information on Unicode code points. The information is retrieved from data modules generated from the Unicode Character Database, or derived by rules given in the Unicode Specification. It and its submodules were copied from English Wiktionary and then modified; see there for more information.

Parameters and functions[edit]

code point[edit]

The code point is to be entered as hexadecimal value. For example:

|A9_hex

|0xA9_hex

|0x00A9_hex

|0x00a9_hex

{{#invoke:Unicode data|lookup|name|0x00A9}} → COPYRIGHT SIGN

"lookup" and "is" functions[edit]

lookup, is: Template-invokable functions that allow access to the functions starting with lookup and is.For most of the functions, add the code point in hexadecimal base as the next parameter. For is"|Latin, is|rtl, and is|valid_pagename, add character string. HTML character references in the text are decoded by the module into code points.; For example, {{#invoke:Unicode data|is|Latin|àzàhàr̃iyyā̀}} → true.

Internally, in modules, these functions are named using underscore: lookup_name|code point ← lookup_name

For &A9; ©: {{#invoke:Unicode data|lookup|name|A9}} → COPYRIGHT SIGN

Data modules[edit]

The data used by functions in this module is found in submodules. Some are generated by AWK scripts on English Wiktionary, others by Lua scripts on the /make subpages of the submodules.

Module:Unicode data/age: 'Age' of a character, that is: version introduction number.
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)
Module:Unicode data/category: data mapping characters to their General Category (from DerivedGeneralCategory.txt)
Module:Unicode data/combining: data mapping characters to their Combining Classes (from DerivedCombiningClass.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/derived core properties:
Module:Unicode data/Hangul: data used to generate the names of Hangul syllables (from Jamo.txt)
Module:Unicode data/names/* (000hh, .., 0E0hh; eg ../names/000): names
Module:Unicode data/scripts: data mapping characters to their Unicode script properties (from Scripts.txt).

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

Character name data modules,
