It is strange. I did some more testing. Whether with xfthb (emacs-27)
or ftcrhb (master), it seems like typing in Persian in *scratch* works
okay. However, if I paste (yank) Persian text, e.g. from Wikipedia,
into *scratch*, the issue surfaces and yanked text is garbled. Further,
Persian text in Gnus's article-mode and in message-mode is always
garbled to begin with. It does seem like a HarfBuzz issue to me.
Please feel free to grab the Vazir font and test for yourself.
Hossein, do you also get this behaviour with Emacs's HarfBuzz?
Any other users using Emacs for Persian or Arabic? I wonder if this
issue happens for other right-to-left languages, e.g. Hebrew.
