Higher level would make use of ranges/language mapping for fallback. DirectWrite fallback is modeled very close if not identical to how this data is defined in .compositefont xml format. When using DirectWrite layout API, application can rely on implicit fonts being selected for different script ranges, and you can set specific language per range to get more accurate results. Newer versions allow user-defined fallback data, and API-wise it's very close to what those files provide. You can certainly parse and discard information irrelevant to freetype, but that will create ambiguity because same script ranges could be mapped to different fonts, and only differ in language. > > > Werner > _______________________________________________ Freetype-devel mailing list Freetype-devel@nongnu.org https://lists.nongnu.org/mailman/listinfo/freetype-devel
