Problem

When running hermes doctor on Windows, the CLI crashes:

UnicodeEncodeError: 'gbk' codec can't encode character '\U0001fa7a' in position 18: illegal multibyte sequence

Root Cause

Windows default console encoding is GBK, which cannot encode Unicode emoji characters like 🩺.

Environment

• Windows 10/11
• Python 3.12
• Hermes 0.8.0

Solution

Replace emoji with ASCII equivalents in doctor.py, or add encoding fallback.

Thanks!
