The *.ttc support for windows stated in this submit by an ex-colleague
of mine is insufficient:
http://sourceforge.net/p/podofo/mailman/message/27461957/
It only works if the *.ttc has a font in it with the platformid = 0
(unicode platform) and if that font has a languageID = 0 (unicode 1.0).
I fixed that issue so that all *.ttc files with a font in them which has
a platformId = 3 (Windows) are supported as long as they have a
languageID equal to the users local LCID or (as fallback) an english
version of the font (id = 1033).
(Details on ttc naming tables:
http://www.microsoft.com/typography/otspec/name.htm)
What has to be done in the future:
- More attributes of the font should be checked e.g. fontstyle,
ps-fontname etc. (now only the fontname will be checked against the
demanded fontname)

Dennis Voss
