Insofar as GSUB tables are processing glyph identifiers and not characters,
this is simply not true. The fact that those fonts may happen to have the
glyphs in question mapped from PUA codepoints in the cmap table is
coincidental, and IMO not best practice.

What glyph IDs do not need is PUA codepoints.
