How Can I Properly Display Unicode Characters in the Windows Console?

Unicode Representation in the Windows Console

When attempting to print strings in the Windows console, developers may encounter the error "UnicodeEncodeError: 'charmap' codec can't encode character." This issue arises from the console's inability to handle certain Unicode characters.

Workarounds:

Python 3.6 and Later:

• Python 3.6 implemented PEP 528, switching the default console encoding to UTF-8. This allows Unicode characters to be displayed directly without the need for workarounds.

Python 3.5 and Earlier:

• Win-Unicode-Console: Install the win-unicode-console package, which enables Unicode support in the console.
• WriteConsoleW() API: Use the WriteConsoleW() API to print Unicode strings directly to the console.
• PYTHONIOENCODING: Set the PYTHONIOENCODING environment variable to ":replace" to replace unencodable characters with the "?" character.

Setting PYTHONIOENCODING:

set PYTHONIOENCODING=:replace

Replacing Characters:

If replacing unencodable characters with "?" is sufficient, you can use the following:

print(u'[\N{EURO SIGN}]')  # Replaces the Euro sign with "?"

Note:

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