openclaw - 💡(How to fix) Fix Dashboard UI renders Chinese agent names as mojibake (UTF-8 displayed as Latin-1)

Bug Description

The Dashboard web UI (http://localhost:18789) renders agent names containing Chinese characters as mojibake (e.g., â™...å... instead of proper Chinese text). Emoji characters are also garbled.

Steps to Reproduce

1. Configure agents with Chinese names/identities in IDENTITY.md (e.g., 麦墨, 麦时, 小麦)
2. Open the Dashboard at http://localhost:18789
3. View the agent selector dropdown or any area displaying agent names
4. Chinese characters appear as garbled Latin-1 text

Expected Behavior

Chinese characters and emoji should render correctly in the Dashboard UI.

Actual Behavior

UTF-8 encoded Chinese characters are displayed as mojibake, suggesting the browser is interpreting the text as Latin-1 instead of UTF-8.

Environment

• OpenClaw version: 2026.5.19
• OS: macOS 15.2 (arm64)
• Browser: Chrome
• Agent names affected: All agents with Chinese characters in their IDENTITY.md name field

Root Cause Hypothesis

The HTML declares <meta charset="UTF-8" /> in dist/control-ui/index.html, but HTTP API responses serving agent name data may be missing Content-Type: application/json; charset=utf-8 header, causing the browser to fall back to Latin-1 encoding.

Screenshot

See attached image — dropdown shows entries like â™... (image-generator), â™... (content-creator), etc. where the emoji + Chinese names should appear.
