Could you describe what rendering issue you're seeing? For example:

- Box-drawing characters showing as garbled text or question marks?
- Missing/broken unicode characters?
- Colors not displaying?
- Layout/alignment issues?

A screenshot would be very helpful — if you can take one, save it and give me the path and I'll look at it. Or you can describe what looks wrong.

Also, what terminal emulator are you using? (e.g., iTerm2, Terminal.app, Windows Terminal, Alacritty, tmux, etc.)


content: This is using tmux, I am accessing via SSH. Broken unicode characters are the main problem

text:
That's the problem — your locale is set to `POSIX` with no UTF-8 support, so all unicode characters render as `__` or similar.

Let me fix it:

content: (Bash completed with no output)


text:
Done. Now you need to reload your shell for it to take effect. The easiest way:

1. **Detach from tmux** (`Ctrl+B` then `D`)
2. **Re-SSH** into the machine
3. **Reattach tmux** (`tmux attach`)

Or from within tmux, run: `! exec bash` to reload your shell in the current pane, then restart Claude Code.

The key fix: your locale was `POSIX` (ASCII only) — now it's `C.utf8` which supports unicode characters.


content: That seems better, excellent


text: Great, glad that fixed it!
