That said, there have been attempts to make so-called “Unicode” fonts which contain a glyph for every character in Unicode. These fonts aren’t suited to general-purpose typography, but are rather a convenience for those without access to a large family of international fonts, or for computer programmers who work with multiscript text and need their displays to be fairly consistent. Because Unicode doesn’t actually specify the shape of the glyph at any particular code point, and because the shape of some of them can vary from language to language, there is no way these fonts can be used to write every given language.
I thought a big problem with writing a “Unicode” font is that the maximum number of characters allowed in a font (e.g. OpenType Font or TrueType font) is much smaller than the Unicode character set.
