Well, according to the TrueType specification, the "symbol" encoding is
used for "Undefined character set or indexing scheme". Basically, this
means that the application must know how the glyphs are encoded within
the fonts, or in this case, that you should add the 0xF000 yourself to
your application..

We could provide this automatic translation to the core library though,
because many (old) Windows font use this so-called encoding.

what's the opinion of other developers/users on the mailing list ??
