[issue23901] Force console stdout to use UTF8 on Windows

[STINNER Victor]

STINNER Victor added the comment:

If sys.stdout is modified, it must be carefully tested in various scenario:

- Windows console, default config
- Windows console, TrueType font
- PowerShell => see #21927, it looks like PowerShell has its own set of Unicode issues
- Redirect output into a file
- etc.

Very good articles by Michael S. Kaplan on Windows stdout/console:
- "Conventional wisdom is retarded, aka What the @#%&* is _O_U16TEXT?"

Good luck...
