Description of Bug and Steps to Reproduce

I think there's a problem rendering Arabic letters with diacritics, even though the font used supports them.

Here's a comparison between foot and ghostty.

Relevant logs, stacktraces, etc.

Foot does not support font shaping ("ligartures", as most people tend to think about it, but it also includes complex scripts, like arabic).

You could try #2278. Though I haven't yet decided if it's something I want to merge.

Closing as duplicate of #57, since most history is in there.
