Basic Questions

Q: How many characters are in Unicode? A: The short answer is that as of Version 13.0, the Unicode Standard contains 143,859 characters. The long answer is rather more complicated, because of all the different kinds of characters that people might be interested in counting.

Unicode font A Unicode font is a computer font that maps glyphs to code points defined in the Unicode Standard. The vast majority of modern computer fonts use Unicode mappings, even those fonts which only include glyphs for a single writing system, or even only support the basic Latin alphabet.

Fonts which support a wide range of Unicode scripts and Unicode symbols are sometimes referred to as "pan-Unicode fonts", although as the maximum number of glyphs that can be defined in a TrueType font is restricted to 65,535, it is not possible for a single font to provide individual glyphs for all defined Unicode characters (143,859 characters, with Unicode 13.0).

...

No single "Unicode font" includes all the characters defined in the present revision of ISO 10646 (Unicode) standard, as more and more languages and characters are continually added to it, and common font formats cannot contain more than 65,535 glyphs (about half the number of characters encoded in Unicode).

As a result, font developers and foundries incorporate new characters in newer versions or revisions of a font, or in separate auxiliary fonts intended specifically for particular languages.
