The tool is usually useful for entering special characters. [1] It can be opened via the command-line interface or Run command dialog using the 'charmap' command.. The "Advanced view" check box can be used to inspect the character sets in a font according to different encodings (), including Unicode code ranges, to locate particular characters by their Unicode code point and to search for ...
A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name. A numeric character reference uses the format &#nnnn; or &#xhhhh; where nnnn is the code point in decimal form, and hhhh is the code point in hexadecimal form.
Hex input of Unicode must be enabled. In Mac OS 8.5 and later, one can choose the Unicode Hex Input keyboard layout; in OS X (10.10) Yosemite, this can be added in Keyboard → Input Sources. Holding down ⌥ Option, one types the four-digit hexadecimal Unicode code point and the equivalent character appears; one can then release the ⌥ Option ...
Unicode was designed to provide code-point-by-code-point round-trip format conversion to and from any preexisting character encodings, so that text files in older character sets can be converted to Unicode and then back and get back the same file, without employing context-dependent interpretation.
In HTML and XML, a numeric character reference refers to a character by its Universal Character Set/Unicode code point, and uses the format: &#xhhhh;. or &#nnnn; where the x must be lowercase in XML documents, hhhh is the code point in hexadecimal form, and nnnn is the code point in decimal form.
The number of code points in each block must be a multiple of 16. A block may contain code points that are reserved, not-assigned, etc. Each character that is assigned, has a single "block name" value from the 338 names assigned as of Unicode version 16.0. Unassigned code points outside of an existing block have the default value "No_block".
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
