In fact the presupposition is false: modern fonts are indexed by
arbitrary glyph indices. They also contain a mapping from Unicode
codepoints to glyph indices for the benefit of naive renderers.
Before someone points out that there is a codepoint for the ffi-ligature,
I'll add that it is present for 1-1 transcodability with MacRoman and
is effectively deprecated.
