Why Am I Getting UnicodeEncodeError in the Windows Console and How Can I Fix It?

Unicode Encoding and the Windows Console

When attempting to print a string in the Windows console, you may encounter the UnicodeEncodeError: 'charmap' codec can't encode character ... error. This stems from the console's inability to display all Unicode characters, especially in older operating systems.

Workaround for Unicode Encoding Errors:

Update: With Python 3.6, PEP 528 has been implemented, changing the default Windows console encoding to UTF-8. This eliminates the need for workarounds.

Original Workarounds:

1. win-unicode-console Package: Install the win-unicode-console package to transparently handle Unicode character display. To use this package, simply install it and run your Python script with the -m run command.
2. Writing to Console Using WriteConsoleW() API: Use the WriteConsoleW() API directly to output Unicode character strings. This requires modifications to your script, but it provides control over character encoding.
3. Replacing Unencodable Characters with '?': Set the PYTHONIOENCODING environment variable to ":replace" to have Python automatically replace unencodable characters with a question mark.
