Probably the best term is "mostly" deprecated. Along with the deprecated gd.c device driver I believe both wingcc and a part of wxwidgets which is normally not used on Linux still use the plfreetype.c approach. I hope no new devices will use it since there are just too many issues (such as all the horrible configuration and run-time stuff to choose fonts by filename as opposed to the more modern approaches that just accept a hint for font family and then the external libraries then grab the glyph from the system font which most closely matches the hint). >> softw...@raven> grep dev_unicode drivers/* >> drivers/aqt.c: pls->dev_unicode = 1; /* wants text as unicode */ > > Is there a way API to query this info via the?

Hazen, would your new general get facility (when propagated to all our languages) be able to detect dev_unicode for the unicode examples? Alan __________________________ Alan W.
