What's Wrong?

Arabic text appears reversed (displayed left-to-right instead of right-to-left) in the Claude Code chat panel in VSCode. This affects both the sidebar and panel locations.

Steps to reproduce:

Open VSCode with Claude Code extension installed
Start a Claude Code chat session
Ask any question that generates Arabic text in the response
Arabic text appears reversed/backwards (characters are in reverse order)
Expected behavior:
Arabic text should render correctly in RTL (right-to-left) direction.

Actual behavior:
Arabic characters are displayed in reversed order (LTR instead of RTL), making the text unreadable.

Environment:

OS: Windows
VSCode version: latest
Claude Code extension: latest
Tested with both "claudeCode.preferredLocation": "panel" and "sidebar" — same issue in both
Additional context:

Setting "terminal.integrated.unicodeVersion": "11" does not fix the issue
The chat webview likely needs dir="rtl" or proper BiDi text handling for Arabic/Hebrew and other RTL scripts

What Should Happen?

RTL
