Problem Statement

Claude Code's VS Code extension does not properly support Right-to-Left (RTL) languages such as Hebrew and Arabic.

When typing in Hebrew, the text is rendered left-to-right (LTR), causing visual inconsistencies, cursor misplacement, reversed word order, and punctuation alignment issues. This makes it difficult to read, edit, and review messages accurately.

As a native Hebrew speaker and developer, I sometimes need to write prompts, explanations, or debugging notes in Hebrew. The current rendering behavior significantly impacts usability and workflow efficiency.

This issue affects both readability and productivity when working in RTL languages within the extension.

Proposed Solution

Add proper RTL (Right-to-Left) text rendering support in the Claude Code chat interface within VS Code.

The ideal experience would include:

• Automatic detection of RTL languages (Hebrew, Arabic)
• Proper bidirectional (BiDi) text rendering
• Correct cursor movement behavior in RTL text
• Proper punctuation and mixed RTL/LTR handling
• Seamless switching between English (LTR) and Hebrew/Arabic (RTL)

This would allow developers who use RTL languages to work naturally and efficiently within the extension.
