Problem Statement

Problem

Claude Code currently has poor support for RTL (Right-to-Left) languages like Hebrew and Arabic. Text appears misaligned, mixed LTR/RTL content (BiDi) renders incorrectly, and the overall readability for Hebrew-speaking users is very poor.

Current behavior

• Hebrew text is displayed without proper RTL direction
• BiDi text (mixed Hebrew + English/code) breaks layout
• Line wrapping and alignment are inconsistent for RTL content

Expected behavior

• Proper RTL rendering for Hebrew and Arabic text
• Correct BiDi handling when mixing RTL text with LTR code/English
• Consistent alignment and readability across all output

Context

Claude Code supports conversation in Hebrew and other RTL languages, but the rendering makes it difficult to use. This affects users across the terminal CLI, VS Code extension, and desktop app.

Environment

• Claude Code CLI (terminal)
• macOS / Linux / Windows
• Languages affected: Hebrew, Arabic, and other RTL scripts
