RTL issue

The Codex desktop app has inconsistent RTL rendering for Persian/Farsi messages. Persian text mixed with English words, punctuation, or inline code is displayed in the wrong direction and becomes hard to read.

Please add proper RTL support or a setting to force message direction for RTL languages.

Language: Persian/Farsi
Platform: Windows
App: Codex desktop app

I’d like to add that this issue is not limited to Persian/Farsi. It also affects Arabic, Hebrew, Urdu, Pashto, and potentially other right-to-left languages.

In Codex, the basic RTL support itself seems to be missing or incomplete.

By contrast, ChatGPT has better RTL support in both the browser and the app, although it still suffers from the same bidirectional text rendering issue described here.

I ran into the same issue and built a small open-source workaround for Codex Desktop RTL rendering.

It fixes mixed Arabic/English direction and keeps code blocks LTR:

Would be happy to hear if it works for your case too.

I ran into this too and built an open-source patch for the Codex desktop app:

⭐ https://github.com/mmnaderi/codex-rtl

It patches the app locally, keeps code/file paths readable in LTR, adds smart RTL/force RTL modes, custom RTL fonts/line-height, and can be reverted with npx codex-rtl --restore.

It’s not a replacement for native upstream support, but it may help Arabic/Hebrew/Persian users meanwhile. I’m the author and would love feedback from people affected by this.

It works fine for RTL, but after running, I lost all my chats on the Codex workspace.
