Feature Request: RTL (Arabic/Hebrew) text support in PowerShell console

Feature Request: RTL Text Support (Arabic / Hebrew)

Problem

When typing or printing Arabic (or any RTL language) in PowerShell (pwsh), letters appear in reversed order visually. This makes it impossible for Arabic-speaking developers to use their native language naturally in the terminal — including for interactive AI tools (e.g. Claude Code, GitHub Copilot) that support Arabic responses.

Expected Behavior

Arabic text should render right-to-left, with letters appearing in the correct reading order — the same way modern editors and browsers handle it.

Current Behavior

Arabic letters appear reversed/mirrored because PowerShell treats all console output as LTR.

Environment

• Shell: PowerShell 7.x (pwsh) — standalone, not inside Windows Terminal
• Console host: Windows Console Host (conhost.exe)
• OS: Windows 11

Suggested Approach

• Respect Unicode Bidirectional Algorithm (UAX Fix the Get-Item Pester test #9) when writing output to the console
• Optionally insert Unicode RTL markers (‏ RIGHT-TO-LEFT MARK) around detected RTL strings on output
• Coordinate with PSReadLine for input-side RTL handling

Impact

Arabic, Hebrew, Persian, and Urdu speakers — a significant global developer community — currently cannot use their native language in PowerShell sessions.
