### Chinese Font Issues in Screenshots
When running AutoClaw inside a Docker container (especially Alpine or Debian Slim), screenshots of Chinese websites may display text as square boxes ("tofu") due to missing fonts.
When running AutoClaw inside a Docker container (especially Alpine or Debian Slim), screenshots of Chinese websites may display text as square boxes ("tofu") due to missing fonts. Emojis (e.g., 🔥) may also appear as squares.
**Solution:** Install CJK (Chinese/Japanese/Korean) fonts in your container.
**Solution:** Install CJK (Chinese/Japanese/Korean) and Emoji fonts in your container.
**For Debian/Ubuntu:**
```bash
apt-get update && apt-get install -y fonts-noto-cjk fonts-wqy-zenhei
apt-get update && apt-get install -y fonts-noto-cjk fonts-wqy-zenhei fonts-noto-color-emoji
```
**For Alpine Linux:**
```bash
apk add font-noto-cjk
apk add font-noto-cjk font-noto-emoji
```
