[QUOTE="velis, post: 1106077, member: 96429"] Seems libraries for this are hard to come by. Further research only turned up [URL='http://www.d-type.com/page/text_engine']d-type[/URL] (commercial), seems pretty powerful. Besides yesterday's [URL='http://www.pango.org/']Pango[/URL] (used in gnome, it seems). I found [URL='http://lists.gnu.org/archive/html/freetype/2006-06/msg00027.html']this page[/URL] where basics are explained. It's not particulary hard to do, but honestly I believe using existing functions, such as the suggested DirectWrite might prove easier / more performant. I have no idea why current approach was taken though. Perhaps there's a specific need for it which makes using such functions impossible. In case it is decided to implement this on top of current renderer, [URL='http://stackoverflow.com/questions/4330951/how-to-detect-whether-a-character-belongs-to-a-right-to-left-language']here's a SO question[/URL] with an excellent answer on how to determine whether a character is RTL or not.
