There is a bug in .agent.md when it contains non-Latin characters and is saved with ASCII encoding.

[KawaCheng]

If .agent.md contains non-Latin characters, such as CJK characters, and is saved in ASCII encoding, the Rovo Dev CLI always crashes when starting with the error message: An unexpected error occurred, exiting.

@KawaCheng That’s a known limitation. The CLI expects UTF-8, and an .agent.md saved as ASCII with CJK characters will crash on start. Re-save the file as UTF-8 without BOM and the CLI will load normally. If it still fails, reinstalling the extension forces a clean parse, but the root fix is the file encoding.
