Bug: RTL (Hebrew) text rendered backwards in Claude Code terminal

Environment:

• Claude Code version: 2.1.63 (also reproduced on 2.1.38)
• OS: Windows
• Terminal: Windows Terminal (PowerShell)
• Also reproduced in: Cursor IDE integrated terminal

Description:
Hebrew (RTL) text is displayed with reversed character/word order in both the input field and Claude's responses. For example, typing "שלום עולם" ("hello world" in Hebrew) displays as "םלוע םולש". This affects both user input and Claude's output.

Steps to reproduce:

1. Open Claude Code in Windows Terminal
2. Type any Hebrew text (e.g. "מה קורה")
3. Observe that the text appears reversed
4. Send the message — Claude's Hebrew response is also reversed

Expected behavior:
Hebrew text should render right-to-left correctly, displaying words and characters in proper reading order.

Actual behavior:
Hebrew text is rendered as if it were LTR, with characters and words appearing in reversed order.

Additional context:

• Running echo "שלום עולם" directly in PowerShell outside of Claude Code displays correctly, confirming Windows Terminal itself supports RTL.
• The issue appears to be in how Claude Code renders text in the terminal, not in Windows Terminal's RTL support.
• The changelog for recent versions mentions a fix for "word deletion and word navigation not working correctly with non-Latin text such as Hebrew" but the visual rendering issue persists.
