Bidirectional text support

[yzn-h]

Describe the solution you'd like
I'd love to be able to write in RTL languages like Arabic and Persian.

Describe alternatives you've considered
there are tools to reverse RTL languages letters like this for Arabic but in egui I cant write RTL letters

Additional context

• great talk link
• Godot engine 4.0 has an excellent implementation

Implementing right-to-left is a lot of work (I know, I've done it before). I rather switch egui to use a crate that does it all for me. I'm not sure which though. I haven't looked at the alternatives in a long while, but I've been keeping my eye on https://github.com/dfrg/swash by @dfrg (https://github.com/dfrg/swash_demo is very impressive).

@emilk Did you make a decision on this ? Any ETA ?

[emilk]

No, I have other things higher on my priority list right now. What's needed first is a bit of research in different text rendering/layout libraries (I mentioned swash above, but there might be other ones to check out).

Hello!

Any plans for this?

[yzn-h]

can't cosmic text be used for egui ?

[parasyte]

Yes, and cosmic text may help with rendering quality as mentioned in #2639 (comment)
