What's Wrong?

The Claude Code CLI fails to properly render or handle Arabic text (Right-to-Left/RTL). When the output contains Arabic characters—or a mix of English and Arabic—the text becomes fragmented, incorrectly aligned, or rendered in reverse. This makes it extremely difficult to read code suggestions, logs, or chat responses, significantly hindering the utility of the tool for Arabic-speaking developers.

What Should Happen?

Claude Code should support bidirectional text (BiDi) in the terminal, correctly displaying Arabic characters and maintaining the integrity of mixed-language (English/Arabic) content. The text should be readable, correctly aligned, and properly formatted without character corruption or layout breaks. that contains the input fields, the user writes his/her message in it, and the AI response

Steps to Reproduce

Steps to Reproduce*

Open your terminal and start Claude.

Ask Claude to explain a concept in Arabic or provide a comment/variable name in Arabic. like "اشرح مفهوم ال evenets في هندسة البرمجيات وما المفاهيم المرتبطة به "

Observe the output in the terminal.

The Arabic text will appear jumbled or mirrored (e.g., words appearing in reverse order or separated characters).

TL;DR

The issue can be mitigated by exploring Unicode and BiDi support in the terminal or using a different terminal that handles Right-to-Left languages correctly.

Guidance

  • Verify that the terminal (PowerShell) supports Unicode and BiDi rendering by checking its documentation or testing with other Arabic text.
  • Check if there are any configuration options in Claude Code or the terminal to enable proper BiDi support.
  • Consider using a different terminal or shell that is known to handle Arabic text correctly, such as Windows Terminal or Git Bash.
  • If possible, test the same commands in a different environment, like a Linux or macOS terminal, to see if the issue is specific to Windows or PowerShell.

Example

No specific code example is provided as the issue seems to be related to terminal rendering rather than code syntax.

Notes

The solution may depend on the specific terminal and operating system being used. The issue might not be directly related to Claude Code itself but rather to how the terminal handles Unicode characters and BiDi text.

Recommendation

Apply workaround: Use a different terminal that is known to handle Arabic text correctly, as the current terminal's limitations might be the primary cause of the issue.
