Terry, the test_winconsoleio problem is issue 38325. Test cases with surrogate
pairs that are known to fail in recent builds of Windows 10 have to be split
out.
For the "ps_AF" locale failure that you noted, in my case with Windows 10
18362, I have to first modify the tests in Lib/test/test__locale.py to set
LC_CTYPE before setting LC_NUMERIC. Otherwise the lconv result in C has the
wrong encoding, and PyUnicode_DecodeLocale fails.
After making this change, I can reproduce the noted failure. The "ps_AF"
(Pashto, Afghanistan) case will have to be skipped in Windows because the
system NLS data does not agree with the assumed Arabic decimal and thousands
separator, U+066B and U+066C, but instead uses "," and ".". This can be
verified directly via WINAPI GetLocaleInfoEx:
>>> n = kernel32.GetLocaleInfoEx('ps-AF', LOCALE_SSCRIPTS, buf, len(buf))
>>> buf.value
'Arab;'
>>> n = kernel32.GetLocaleInfoEx('ps-AF', LOCALE_SDECIMAL, buf, len(buf))
>>> buf.value
','
>>> n = kernel32.GetLocaleInfoEx('ps-AF', LOCALE_STHOUSAND, buf, len(buf))
>>> buf.value
'.'
In case this was a quirk in the NLS data for languages that use a Perso-Arabic
script, such as Pashto, I also checked Saudi Arabia ("ar-SA"), which uses a
standard Arabic script, but the result was the same.
