Normally, CJK characters don't contain TrueType hints at all since this would approximately double the file size. Instead, bitmap strokes are provided for the most common characters at the most common ppem sizes. In other words, improvements in rasterizing CJK fonts is usually coming from the patches to the auto-hinter.
Hi, Werner Thanks for the detailed tech explanation! really learned a lot! CJK fonts used for screen display do contain TrueType hints, at least for common used ones (both proprietary and open source). So their sizes are...nearly 20 MB for a single font. eg: Microsoft YaHei/JhengHei, Apple Hiragino sans GB, STheiti and open source wqy-micro-hei and wqy-zen-hei. Old and bitmap fonts are nearly not usable for CJK fonts. Can you imagine the looking a character like 斡 displayed in 10px.......some strokes will even disappear...so a tiny adjustment is a must (hinting) and the hinting algorithms are important too (at least freetype's current one can't fulfill the needs), or it'll be even worse than without hinting. Anyway we discussed tech details of Freetype and Infinality in this thread because we want to know if infinality is acceptable for OBS. So can you please answer this question?
