Modul:Unicode data
 | Predloga se uporablja na številnih straneh. Z urejanjem te predloge lahko zelo obremenite strežnike, zato pred uvedbo vse spremembe, ki jih želite uvesti, preizkusite na njenih podstraneh (/peskovnik oziroma /testniprimeri) ali na svojih lastnih podstraneh. Preizkusite jih lahko tudi v posebnem peskovniku za predloge. Preizkušene spremembe se lahko v predlogo dodajo z enim samim urejanjem.

Usage
[uredi kodo]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
[uredi kodo]code point
[uredi kodo]The code point is to be entered as hexadecimal value. For example, U+00A9 © COPYRIGHT SIGN:
- |A9hex
- |0xA9hex
- |0x00A9hex
- |0x00a9hex
{{#invoke:Unicode data|lookup|name|0x00A9}}→ <reserved-00A9>
Incorrect or unintended results:
- 169dec:
{{#invoke:Unicode data|lookup|name|169}}→ <reserved-0169>
—"U+00A9" ©expected; but is read as 00A9hex (that is, 361dec - U+00A9
{{#invoke:Unicode data|lookup|name|U+00A9}} —do not use "U+" prefix - غ
{{#invoke:Unicode data|lookup|name|غ}} —cannot enter a character as codepoint
"lookup" and "is" functions
[uredi kodo]lookup, is- Template-invokable functions that allow access to the functions starting with
lookupandis.For most of the functions, add the code point in hexadecimal base as the next parameter. Foris|Latin,is|rtl, andis|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}}→ <reserved-00A9>

Data modules
[uredi kodo]The data used by functions in this module is found in submodules. Some are generated by AWK scripts shown at User:Kephir/Unicode 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/Unihan/kCantonese/*: kCantonese pronunciation property
- Module:Unicode data/names/* (000hh, .., 0E0hh; e.g. ../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.
