Yes, that's obviously true, but the problem is that I don't have tables for each language indicating the required codepoints, all I have are tables listing Unicode values in encodings traditionally used for each language. These tables almost always include a few (1-5) glyphs which many fonts are missing. So, the test is to require that the number of missing glyphs for non-Han languages is very small (<8) to allow fonts which happen to be missing only a few unimportant glyphs to be used. Discovering which glyphs in each encoding are problematic in many fonts would allow this fudge factor to be reduced further. > So, the tests for CJK languages and for other languages are clearly different, > only CJK languages can go with testing only a "signifiant fraction", > for all other languages all chars must be tested. Yes, the tolerance value given for the Han languages is 500 codepoints while the value for non-Han languages is two orders of magnitude smaller.
