[ft] True Type Collection (TTC) shared glyph tables

[awiederman]

If I use a True Type Collection (TTC) font file when initializing my FreeType
Face, is there anything special I need to do to render a character that is
part of the shared table in the TTC (but not part of the individual TTF)?

At the moment FT_Get_Char_Index is returning 0 for the CJK Ideograph at
U+7380, and the error symbol is being used.  However, if I open this font
file in Windows' Character Map program it shows that this character is part
of the font.  Additionally, another program I installed called Typograf will
show that this character exists in the font.  I've tested a few other font
programs (like FontForge, Font Creator, and dp4 Font Viewer) and none of
these programs recognize that this character exists in the font, though.  So
I am led to believe that this character is part of the shared glyph table,
and only some of these programs are set up to look there.

Is there a way for me to verify that this character actually is part of the
shared TTC table?  Additionally, is there a way for me to access it using
FreeType if it does indeed exist in the shared table?  Should this be
happening automatically, or is there an error with how I'm setting up the
FreeType Face?

Any insight into TTC font files or this specific issue would be appreciated. 
Thanks!
