This has been recently discussed on the mailing list; see for example http://lists.gnu.org/archive/html/freetype/2010-02/msg00065.html which also shows an image of a debugging session with Arial. Hopefully, this clarifies the issue. > If it's a bug I would be happy to help fixing it, It's not a bug.

This is not possible. Werner _______________________________________________ Freetype mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/freetype
