JISX0201 is an obsolete encoding, and in generally you want to _avoid_ getting characters (half-width Kana) from it. I believe JISX0212 characters would be in a large font containing JISX0208 characters as well. In neither case would I expect a separate font; the basic set of Japanese characters are those in JISX0208. (Hmm, thought of one case where coverage matching may cause a little trouble ... there exists fonts of "just kana" that are meant to replace the kana part in a complete font. In theory, you should be able to have: "My Kana Font, My Complete Font" As part of your "Sans" alias and get the right effect; mostly, those those fonts are for typographical purposes so wouldn't be part of a generic alias, however.) > > My impression is that the better fonts have set the CodePageRange > > bits.
