The function now sets temporarily the LC_CTYPE locale to the locale of the category that determines the requested value if the locales are different and the resulting string is non-ASCII. This temporary change affects other threads.

LGTM. I wrote a similar change in the past using _Py_GetLocaleconvNumeric(). It's used for example in Python/formatter_unicode.c to get the decimal point and thousands separator.

Yes, I used your #4174 as an example. |

You don't call nl_langinfo() twice anymore? Why changing the code?

Because I now think that it was not needed. The result can only be changed if setlocale() is called with the same category or LC_ALL. And, even if it is not explicitly stated, I think that calls setlocale(..., NULL) are not counted.
On other hand,I want to avoid duplication of the code for conversion of the result because of #124974.

locale.localeconv() calls localeconv() only once, whereas it changes the LC_CTYPE locale while reading its output. Let's do the same for nl_langinfo(). If the assumption is wrong, we can adjust the code later.

LGTM with a single call to nl_langinfo().
