How Can I Print Unicode Characters in the Windows Console Without Encoding Errors?

Printing Unicode Characters in the Windows Console

When encountering the error "UnicodeEncodeError: 'charmap' codec can't encode character," it indicates that the console encoding cannot handle certain Unicode characters. To resolve this, Python 3.6 onwards has implemented UTF-8 as the default Windows console encoding, allowing the display of all Unicode characters.

Alternative Workarounds:

For earlier Python versions, consider the following solutions:

• win-unicode-console Package: This package transparently calls WriteConsoleW() API, which supports Unicode characters. Use py -m pip install win-unicode-console and py -m run your_script.py.
• PYTHONIOENCODING Environment Variable: By setting PYTHONIOENCODING to ":replace," you can automatically replace unencodable characters with the question mark "?". Use set PYTHONIOENCODING=:replace and python3 -c "print(u'[N{EURO SIGN}]')".

Limitations in Interactive Consoles:

In Python 3.6 , the PYTHONIOENCODING encoding is ignored for interactive console buffers unless PYTHONLEGACYWINDOWSIOENCODING is set to a non-empty string.
