# Claude Code configuration

## Statusline (`statusline-command.sh`)

The custom statusline script renders **only ASCII-safe characters and ANSI color codes**:

- ASCII brackets `[ ]` for git branch and effort level
- ANSI 256-color escape sequences for model names, effort levels, and rate-limit percentages
- The `¥` symbol (U+00A5) for CNY balance in DeepSeek output

It does **not** use Nerd Font glyphs, powerline separators, or emoji.

### Unicode symbols you may see in the TUI

Some symbols that appear in the Claude Code interface are **rendered by Claude Code's own TUI**, not by this statusline script. For example, arrow symbols such as `⏵` (used before "bypass permissions on" prompts) are drawn by Claude Code itself.

If these symbols display as boxes or question marks, install a Unicode-capable font such as:

- **Noto Color Emoji** (recommended on Linux)
- Any terminal font with full Unicode support

To install Noto Color Emoji on Debian/Ubuntu:

```bash
sudo apt-get install -y fonts-noto-color-emoji
```

The statusline script itself does not require emoji fonts.
