That's true, but font-matching is not quite as simple as matching string characters against a set of available Unicode characters. Each grapheme cluster needs to be rendered entirely in a single font. If different characters in the grapheme cluster map to different fonts, it needs to be clear how to resolve to a single font. ~fantasai
