gh-52551: Use wcsftime() to implement time.strftime() on Windows

[serhiy-storchaka]

• Issue: time.strftime() and Unicode characters on Windows #52551

[vstinner]

There are compiler warnings: 'HAVE_WCSFTIME': macro redefinition [D:\a\cpython\cpython\PCbuild_freeze_module.vcxproj]

Oh, I did not find where it was defined in C.

Is #54862 issue solved on Windows?

What exactly is that issue about? I get no mojibake:

>>> import time
>>> time.strftime('%Z')
'Фінляндія (літо)'
>>> time.tzname
('Фінляндія (зима)', 'Фінляндія (літо)')

But it crashes on invalid format string (like %f).

Well, this was unrelated.

I changed my Windows language to French and the timezone to UTC+14, I managed to get a non-ASCII timezone name:

vstinner@WIN C:\victor\python\main>python
Python 3.14.0a1+ (heads/pr/125658:0e1bdf72d94, Oct 18 2024, 16:46:59) [MSC v.1941 64 bit (AMD64)] on win32
>>> import time; time.strftime("%Z")
'Îles de la Ligne '

So at least for this locale (French_France.1252), it works as expected.

LGTM
