This is definitely and advanced topic and possibly needs a hack that I am willing to do.
I edit Arabic files quite a lot. Arabic characters displayed by Terminal.app are not playing nice at all. To top that, some custom fonts that I use are getting picked up as alternatives for certain glyphs in my
The default font for displaying English works fine and I have no complains about it.
However, I want to change the font picked by Terminal.app when displaying other languages, in my case it is Arabic.
To answer this question, one must know if it is even possible. Are the fonts hardwired into the binary? Is there a hack to bypass that?
It turns out the only hack to solve this problem wasn't a hack. It is the best of what the OS offers for eligible Fixed Arabic Font and that is
Courier New. The font can be read very clearly except for "ARABIC LETER HEH INITIAL FORM" Unicode
FEEB. Hopefully someday someone will fix that letter for better reading in the terminal. Or just copy those glyphs over to Menlo.
