I have a question about Unicode font updates. I'm trying to make flash cards for all the stokes (笔画)but I but I can't get some of them to properly render as the flash card headword. I know the 6.1 update for Unicode includes these CJK strokes but I'm wondering is there some way I can update the fonts on my iOS device or is this something that I would have to wait for Pleco as the developer to update?
