• Your operating system(s) : Windows10
• Your Python version: 3.7.0
• Your fbs version 1.1.3 pro
• Your PyInstaller version 5.1
• Your PyQt / PySide version 5.15.6

When the app_name configured in the settings/base.json file is Chinese, executing fbs freeze will report the following error. When I change the app_name to English, it works fine. But my business needs app_name in Chinese, how can I fix this problem?

This seems like a regression in PyInstaller 4.7 (source). Are you able to downgrade to an older PyInstaller version?
