分析

• The error shows a character encoding issue when Python tries to read files using the system’s default encoding (GBK) on your Windows system. This is a common problem when working with packages that contain non-ASCII characters.

Here’s how you can fix it:

# Create a file named fix_encoding.py with this content
import sys
import locale
import pathlib

# Force UTF-8 as default encoding
def force_utf8():
    # Save original read_text method
    original_read_text = pathlib.Path.read_text
    
    # Create patched version that defaults to utf-8
    def patched_read_text(self, encoding=None, errors=None):
        if encoding is None:
            encoding = 'utf-8'
        return original_read_text(self, encoding=encoding, errors=errors)
    
    # Apply the patch
    pathlib.Path.read_text = patched_read_text

if __name__ == "__main__":
    force_utf8()
    
    # Run the original script
    if len(sys.argv) > 1:
        exec(open(sys.argv[1], encoding='utf-8').read())

执行修复

python fix_encoding.py D:\XTRANS\cuda\03-graph-db\04-cmkg\pdf2zh-v1.9.9-with-assets-win64\pdf2zh\gui.py

或者：设置环境

• Alternatively, you can modify your environment by setting the PYTHONIOENCODING environment variable:
• This forces Python to use UTF-8 encoding for file operations.

set PYTHONIOENCODING=utf-8
python D:\XTRANS\cuda\03-graph-db\04-cmkg\pdf2zh-v1.9.9-with-assets-win64\pdf2zh\gui.py
