With very few exceptions, almost all CJK fonts are *partically* hinted. (I'm not familiar with fonts for other scripts, but I guess there are some more with similar situations.) That means most of the CJK fonts will not work well in Fedora. > According to Freetype upstream, you should remove all hinting bytecode from > the fonts if it's not complete. > Please go through your fonts, especially non-Latin fonts, looking for > hinting bytecode, and if it isn't anywhere near complete, please remove it > from the font. It may be acceptable for a short term workaround, but I don't think it is an appropriate solution. We could remove those partial hints from all the Fedora distributed fonts, but we have no control over other fonts; there are many free or commercial CJK fonts other than those packaged in Fedora, that are partially hinted. If we go you-should- remove-all-partial-hints-if-you-want-to- use-it-on-Fedora direction, Fedora users will be effectively unable to use those fonts, that IMHO is not a good idea. What happens if I propose Fedora to simply exclude those bytecode support in Fedora distribution of FreeType, as in the past? _______________________________________________ fonts mailing list fonts@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/fonts http://fonts.fedoraproject.org/
