Additional information

No response

Start at kimi_cli/ui/print/visualize.py, especially feed at line 80 and visualize at line 191, where the traceback reports the failure. Reproduce the CLI call on Windows with the GBK console and a response containing U+0133; done means the task completes without UnicodeEncodeError and the output remains readable.
