New submission from Egor Tensin:
I've come across an issue of Python 3.5.1 appending an extra newline when
print()ing non-ASCII strings on Windows.
This only happens when the active "code page" is set UTF-8 in cmd.exe:
>chcp
Active code page: 65001
Now, if I try to print an ASCII character (e.g. LATIN CAPITAL LETTER A),
everything works fine:
>python -c "print(chr(0x41))"
A
>
But if I try to print something a little less common (GREEK CAPITAL LETTER
ALPHA), something weird happens:
>python -c "print(chr(0x391))"
Α
>
For another example, let's try to print CYRILLIC CAPITAL LETTER A:
>python -c "print(chr(0x410))"
А
>
This only happens if the current code page is UTF-8 though.
If I change it to something that can represent those characters, everything
seems to be working fine.
For example, the Greek letter:
>chcp 1252
Active code page: 1253
>python -c "print(chr(0x391))"
Α
>
And the Cyrillic letter:
>chcp 1251
Active code page: 1251
>python -c "print(chr(0x410))"
А
>
This also happens if one tries to print a string with a funny character
somewhere in it. Sometimes it's even worse:
>python -c "print('Привет!')"
Привет!
�т!

Look, guys, I know what a mess Unicode handling on Windows is, and I'm not even
sure it's Python's fault, I just wanted to make sure I'm not delusional and not
making stuff up.
Can somebody at least confirm this? Thank you.
I'm using x86-64 version of Python 3.5.1 on Windows 8.1.
