Hey, thanks for the feature request. RTL and bidirectional support in Chat is something that comes up regularly, so you’re not the only one asking.
To avoid splitting votes across multiple threads, please add your vote and your use case Hebrew or Arabic to the main thread: Add RTL for chat
Honest status update: it’s on the radar, but there’s no specific implementation timeline right now. Handling mixed LTR and RTL, code blocks, and markdown correctly isn’t as simple as dir="auto", so it’s more work than it looks at first. If there’s an update, it’ll be posted in that thread.
