What's Wrong?

Every command run in the VS Code integrated terminal via Claude Code produces garbled output. Text characters are replaced with stray Unicode diacritical marks and unreadable symbols instead of normal ASCII/Latin output.

The corrupted output affects all commands run through Claude Code in the terminal. Notably, after exiting and reloading VS Code several times, the issue resolves itself — and even the previously garbled output in the terminal history appears normal again, suggesting a rendering/state issue rather than data corruption.

What Should Happen?

All commands run via Claude Code in the VS Code terminal should display clean, correctly-rendered ASCII/Latin text output at all times — without any Unicode diacritical corruption or garbled symbols.

Steps to Reproduce

  1. Open VS Code with the Claude Code extension active.
    1. Open a project in VS Code.
    1. Ask Claude Code to run any shell command in the integrated terminal (e.g., git status, ls, npm install).
    1. Observe the terminal output — text appears garbled with stray Unicode diacritical characters and unreadable symbols instead of normal output.
    1. Exit VS Code completely and reopen it.
    1. Repeat steps 2–4 and observe the same garbled output.
    1. After exiting and reloading VS Code several more times, the output eventually appears normal — and previously garbled history also looks correct.

Key observation: The garbled output is transient/ephemeral — after reloading VS Code several times the issue self-resolves, and even previously garbled history appears normal. This strongly suggests a terminal rendering/state issue rather than actual data corruption.
