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.
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 ...
However the XML and HTML standards restrict the usable code points to a set of valid values, which is a subset of UCS/Unicode code point values, that excludes all code points assigned to non-characters or to surrogates, and most code points assigned to C0 and C1 controls (with the exception of line separators and tabulations treated as white ...
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

A block is a uniquely named, contiguous range of code points. It is identified by its first and last code point. Blocks do not overlap. 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 ...
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.
GNOME Character Map, formerly known as Gucharmap, is a free and open-source software Unicode character map program, being one of the GNOME Core Applications. This program allows characters to be displayed by Unicode block or script type. [3] It includes brief descriptions of related characters and occasionally meanings of the character in question.
