Well, handling of IDCs is beyond FreeType.  Similar to the reordering
of Indic and Arabic characters, this must be handled at a higher
level.  If Freetype actually sees character codes of the IDC block, it
should render them as-is.  Thus I believe it makes sense to add them
to the CJK ranges of the autofitter.
