Templat ini menghasilkan deskripsi terformat untuk suatu karakter [[Unicode]], yang dipakai ''in-line'' dalam teks biasa. 
* Karakter {{tlx|unichar|<nowiki>a9|Copyright sign</nowiki>}} is about intellectual property. &rarr; The character {{unichar|a9|Copyright sign}} is about intellectual property.

== Penggunaan ==
This template produces a ''formatted description'' of a [[Unicode]] character, to be used ''in-line'' with regular text. It needs Unicode hexadecimal value and name as input, like <code><nowiki>{{unichar|00A9|Copyright sign}}</nowiki></code> &rarr; {{unichar|00A9|Copyright sign}}.

It follows the standard Unicode presentation of a character such as using the pattern "U+00A9", and allowing Unicode's all caps naming habit (which is undesired in Wikipedia text) by using {{smallcaps|small caps}}. The hexadecimal value is required (e.g. A9), other input is optional. The actual glyph is looked for in a font that covers Unicode quite well, and this can be set more specific to e.g. language or IPA-specialized fonts. To show the glyph, the font character can be overridden with an image. A wikilink to an article and another to Unicode can be created, it is possible to add (in brackets), the calculated decimal value, HTML-notations, and a note.

Some special code points are given extra care, like controls and space characters. These special code points are automatically detected by the [[Template:unichar/gc|unichar/gc]] sub-template.

=== Contoh ===
* <code><nowiki>{{unichar|00A9|Copyright sign}}</nowiki></code> &rarr; {{unichar|00A9|Copyright sign}}
* <code><nowiki>{{unichar|00A9|Copyright sign|nlink=Copyright symbol}}</nowiki></code> &rarr; {{unichar|00A9|Copyright sign|nlink=Copyright symbol}}
* <code><nowiki>{{unichar|00A9|Copyright sign|nlink=Copyright symbol|note=See also [[Copyleft]] symbol}}</nowiki></code> &rarr; {{unichar|00A9|Copyright sign|nlink=Copyright symbol|note=See also [[Copyleft]] symbol}}
* <code><nowiki>{{unichar|00A9|Copyright sign|nlink=Copyright symbol|dec=|html=}}</nowiki></code> &rarr; {{unichar|00A9|Copyright sign|nlink=Copyright symbol|dec=|html=}}
* <code><nowiki>{{unichar|00A0|No-break space|note=NBSP}}</nowiki></code> &rarr; {{unichar|00A0|No-break space|note=NBSP}}
* <code><nowiki>{{unichar|0007|nlink=Bell character}}</nowiki></code> &rarr; {{unichar|0007|nlink=Bell character}}

=== Parameter ===
The blank template, with all parameters, is as follows:
<pre>
{{unichar
| <!-- hex value, code point (do not add the "U+")  -->
| <!-- Unicode name -->
| ulink =
| image =
| cwith =
| size  =
| use   =
| use2  =
| nlink =
| dec   =
| html  =
| note  =
}}
</pre>

Inline version:
<pre>
{{unichar| <!-- hex value (do not add "U+") -->| <!-- Unicode name -->|ulink= |image= |cwith= |size= |use= |use2= |nlink= |dec= |html= |note= }}
</pre>

* '''First parameter''', '''1=''' Unnamed, required (prefix "1=" may be omitted). The hexadecimal value of the code point, e.g. {{code|00A9}}.
:''Notes'': The parameter accepts input like {{code|A9}}, {{code|a9}} and {{code|00A9}} as hexadecimal value. Decimal values are not detected being decimal, and will give unexpected results (see Error messages, below).

* '''Second parameter''', '''2=''' Unnamed (prefix "2=" may be omitted). The Unicode name of the character. The template uses this input as the {{Smallcaps|name in small caps}}, forced into these small capitals whatever the input. This name may differ from the name of the corresponding Wikipedia article (see below: nlink=).

* '''nlink=''' Optional.wikilink.  Name of the Wikipedia page that will be linked to. If used, the Unicode name (second parameter) has a wikilink to the article. When the article name and the Unicode name are the same, using a straight "nlink=" without a name will do. <br/>
::For control characters using the ''nlink'' parameter, the Unicode name parameter is not used: the ''nlink'' parameter is displayed instead, without small caps.
:''Note'': the name of the page is case sensitive as with all wikipages.

:<code><nowiki>{{unichar|00A9|Copyright sign|nlink=Copyright symbol}}</nowiki></code> &rarr; {{unichar|00A9|Copyright sign|nlink=Copyright symbol}}
:<code><nowiki>{{unichar|00A3|Pound sign|nlink=}}</nowiki></code> &rarr; {{unichar|00A3|Pound sign|nlink=}}.

* '''ulink'''  Optional. Creates a wikilink in the "U+" prefix. When used without name ({{code|ulink={{!}}}}), the default value, [[Unicode]] page, is used: [[Unicode|U+]].

* '''dec=''' Optional. Adds the decimal value to the text, in the bracketed note.

* '''html=''' Optional. Adds the HTML character reference to the text, like <code>&amp;#160;</code> in the bracketed note. If a ''named character reference'' exists, like <code>"&amp;nbsp;"</code>, that is added too.

*'''use=''' Optional. Sets the font-hinting template to get the glyph, since the character may not be present in a regular browser font. Default is {{tl|unicode}}, other options are {{tl|IPA}}, {{tl|lang}} and {{tl|script}}. When setting "use=lang" or "use=script", '''use2''' should be used to set the language ("use2=fr") or the script ("use2=Cyrs"). A glyph may still not show as expected due to browser effects. For a detailed description, see the templates documentation.
: <code><nowiki>{{unichar|0485|COMBINING CYRILLIC DASIA PNEUMATA|cwith=|use=script|use2=Cyrs}}</nowiki></code> &rarr; {{unichar|0485|COMBINING CYRILLIC DASIA PNEUMATA|cwith=|use=script|use2=Cyrs}}

* '''image=''' Optional. Allows for a ''file'' (graphic image) to represent the glyph, overrules the font completely. The filename should include the extension like ".svg", but ''not'' the prefix "File:".

* '''cwith=''' Optional. Useful when the Unicode character is ''combining''. Using {{code|1=cwith=}} adds a space before the character, allowing the combining effect. So when used with a character like {{code|1=cwith=a}}, the character will be combined with the letter "a". In Unicode, a general glyph used to place a combined character is {{unichar|25CC|DOTTED CIRCLE|html=}}.
: without '''cwith=''':
::<code><nowiki>{{unichar|0485|COMBINING CYRILLIC DASIA PNEUMATA}}</nowiki></code> &rarr; {{unichar|0485|COMBINING CYRILLIC DASIA PNEUMATA}}
: '''cwith=''' without parameter:
::<code><nowiki>{{unichar|0485|COMBINING CYRILLIC DASIA PNEUMATA|cwith=}}</nowiki></code> &rarr; {{unichar|0485|COMBINING CYRILLIC DASIA PNEUMATA|cwith=}}
: '''cwith=''' with dotted circle:
::<code><nowiki>{{unichar|0485|COMBINING CYRILLIC DASIA PNEUMATA|cwith=&amp;#9676;}}</nowiki></code> &rarr; {{unichar|0485|COMBINING CYRILLIC DASIA PNEUMATA|cwith=&#9676;}}

* '''size=''' Optional. Can be used to set the size ''of the glyph''. By default "size=125%". For the font, all font-size style inputs are accepted: "7px", "150%", "2em", "larger".
:<code><nowiki>{{unichar|0041|LATIN CAPITAL LETTER A|size=2em}}</nowiki></code> &rarr; {{unichar|0041|LATIN CAPITAL LETTER A|size=2em}}
: When using an ''image'' (file) instead of a font, this size can only accept sizes in px like "12px". Default for images is "10px" .

<pre>
{{unichar
| A9
| Copyright sign
| ulink = Unicode character mapping
| image = 
| size  = 150%
| nlink = Copyright symbol
| note  = Example
}}
</pre> Produces:
* {{unichar
| A9
| Copyright sign
| ulink = Mapping of Unicode characters
| image = 
| size  = 150%
| nlink = Copyright symbol
| note  = Example
}}

=== Efek Presentasi ===
Since this template is aimed at presenting a ''formatted, inline description'', some effects are introduced to sustain this target.
* '''Showing space characters''': All space characters (those with [[Unicode_character_property#General_Category|General Category]]: Zs) are presented with a light-blue background, to show their actual presence and width: <code>{{unichar|00A0|No-break space|nlink=NBSP}}</code>.
:Incidentally, the regular space <nowiki> </nowiki> is replaced with <code>&amp;#00A0;</code> (NBSP) to prevent wiki-markup deleting it as repeated spaces.

* '''Removing formatting characters''': Formatting characters (those with [[Unicode_character_property#General_Category|General Category]]: Cf, Zl and Zp) are removed from the output. By definition, formatting characters have no glyph. By removing them they cannot have a formatting effect.

Exception: five Arabic Cf/formatting number markings U+0600..U+0603 and U+60DD, are shown. While Cf formatting characters usually have no glyph, these five have. By internally adding "(visible)" to the category, these characters are shown.

*'''Removing whitespace''': The template removes formatting code and surrounding whitespace from the input. A <Return> in the Name-input (possibly unintended) would frustrate the in-line behaviour expectation.

* '''Showing a label like <control-0007>''': Unicode states, that an code point has ''[[Unicode character property#General Category|no name]]'' when it is one of these: a control character, a private use character, a surrogate, a not assigned code point (reserved), or a non-character. These code points instead should be referred to by using a "Code Point Label", such as <private-use> or <private-use-E000>. In this situation, this template ''replaces'' the glyph with that label. This way, the correct presentation wins it over Unicode-usage to the letter of the law.
* "Control" general category=Cc: <code><control></code> or <code><control-''0007''></code>
* "Surrogate" general category=Cs: <code><surrogate></code> or <code><surrogate-''D800''></code>
* "Private Use": general category=Co: <code><private-use></code> or <code><private-use-''FFA0''></code>
* "Not a character" (minus the reserved code points, see below): general category=Cn: <code><not-a-character></code>, <code><non-character></code> or <code><not-a-character-''FFA0''></code>

The second parameter (Unicode name) is not presented, since it cannot exist. It is possible to create a link to a article.
:''Note'': A <reserved> (unassigned) code point cannot be detected yet, and so is not presented with this label. These code points too are given Cn category.
:(Background on <>-labels: A Name can never have <>-brackets at all. These rules prevent mixing up a name with an actual control-character. So it will not happen that a [[Bell character|bell]] rings when a page is opened that contains a Name of U+0007).

=== Kemungkinan kesalahan ===
* The template produces an {{error|Error-message|tag=span}} when parameter #1 (hex value) is missing.
* A non-hexadecimal input like ''00G9'' produces an error (Because ''G/g'' is not hexadecimal).
* Do not add the U+-prefix like ''U+00A9''. It will not be recognised.
* If the template ''only'' shows the code point number, like "{{unicode|2038}}", you're probably using the wrong template {{tlb|unicode}}, instead of {{tlb|unichar}}.
* The glyph may be overruled and changed into a ''label'' like <control-0007>. These characters have no Unicode name. An nlink will be directly to the article (entered in "nlink=Bell signal"). A blank like this "nlink=", (which links fine for regular characters like Pound sign), cannot work for <labeled> characters (there is no character name at all to make into a link). This produces an error.
* A decimal value input like ''1=98'' will be read as being hexadecimal value 0098. There is ''no way'' that the template can detect you intended to enter 98<sub>10</sub>=62<sub>16</sub>.No warning is issued, and the wrong character, U+0098<sub>16</sub>, will be shown (''not'' U+0062).

===Catatan Teknis ===
The word "unichar" is used only in this English Wikipedia, as a name for this template. It has no meaning outside.<br>

The template uses these subtemplates:
* {{tl|unichar/main}} Accepts all the input from {{tlx|unichar}}. Calls several subtemplates to produce the textstrings, and then strings them together. Also checks for the error non-hex input.
* {{tl|unichar/ulink}} creates a piped link for the "U+" prefix.
* {{tl|unichar/gc}} determines the Unicode general category, when this category is special (like, for control characters).
* {{tl|unichar/glyph}} for rendering the glyph by font. Accepts "image=" that overrules the font. Uses also "use", "use2", "size", "cwith".
* {{tl|unichar/na}} Produces the formatted name of the character in {{Smallcaps|smallcaps}}. Accepts the "nlink=" to create a piped wikilink to an article. When the [[Unicode_character_property#General_Category|general category]] (gc) is special, the name will change into a <''label''-''hhhh''>.
* {{tl|unichar/notes}} - Produces the three optional notes in brackets: ''decimal value'', ''HTML-character reference'' (both decimal and by name like {{code|&amp;nbsp;}} if that exists using {{tlx|numcr2namecr}}) and the free text ''note'' as provided by the editor. Also does the brackets themselves.

* Using the main template as an input-easy feature, there are few calculations done (actually only two hex2dec), and allows for adding default values not too deep in the templates.

* The value "<#salted#>" is used internally to pass through a non-defined input parameter. This value is correct when about the Name, because a Unicode name cannot have the characters <##>, and so [[Salting the earth|salted]] is the right word (meaning uninhibitable). For ease of code maintenance it is used in more places around.

====Issues====
* Unassigned code points, to be labelled <reserved>, cannot be detected.
* When using use-script, use2 needs lowercase (e.g. 0485, Cyrs or cyrs)
