Arabic Support and Bidirectional Text

[eid-setf]

Greetings, first I would like to thank all of you for your efforts in making this amazing Emacsen, and giving us a small taste of the dream that is CL Emacs, even though there aren't as much CL programmers as Emacs Lisp ones, so making this editor with such wide range of capabilities is quite an accomplishment that should be appreciated!

Though I think that multilingual support is quite lacking, especially for bidirectional languages (languages that go from right to left like Arabic and Hebrew) and languages where letters are shaped differently depending on their position in the word (e.g. Arabic and Farsi). This in turn is stopping a big portion of programmers from using Lem.

Currently All I see is Unicode blocks instead of Arabic letters and I don't know if it's just a font problem, but if it turns out to be bigger than that I'm willing to help with my tiny amount of Lisp knowledge and as a native Arabic speaker.

Thanks again for your amazing efforts, it really can't be overestimated how inspiring this is.

Hello, thank you for your issue.
First, I think the problem lies in the fact that the developers of Lem are only from English-speaking and Japanese-speaking regions.
I have no understanding of Arabic at all, and I don't fully grasp the concept of how the shape of letters changes depending on their position.
When it comes to implementing bidirectional text support, it also sounds like a very difficult problem.
Although, considering the population of Arabic speakers, I believe it is worth supporting in Lem, and I would love to make it happen.
If you could take the lead in this effort, I would be truly grateful.
I'd appreciate help you.
