As I already added U+06C1 ARABIC LETTER HEH GOAL to the list of
required characters for displaying Arabic, the question is now: are
there fonts inappropriate for Arabic that support U+06C1, but do NOT
support U+06D2 ARABIC LETTER YEH BARREE?  If there are such fonts,
then we should add U+06D2 to the list of required characters as well.
