Hmm. Then `ftview`'s default cache size should probably be increased
to cover both the number of characters/glyphs in Arabic and Indic
scripts, including (most of) the necessary ligatures. If I call
`ftview ArefRuqaaInk-Regular.ttf`, a bit more than 200 glyphs are
shown; IMHO this *must* fit into the cache.
Am I missing something?
