I am in investigating in similar lines, I think the following explanation
can help.

The locale argument to the setlocale, _wsetlocale, _create_locale, and
_wcreate_locale is
locale :: "locale-name"
| *"language[_country-region[.code-page]]"*
| ".code-page"
| "C"
| ""
| NULLFor GetLocaleInfoEx locale argument is *<language>-<REGION>* <language>-<Script>-<REGION> As we can see _create_locale will also accept the locale appended with code-page but that is not the case in lateral. The important point is in our current issue we need locale name only and both functions(GetLocaleInfoEx, _create_locale) support an equal number of locales names if go by the syntax of the locale described on Microsoft documents. With that thought, I am parsing the input string to remove the code-page and give it as input to GelLocaleInfoEx. I have attached the new patch. > How have you ensured the testing of this code?

I don't know how to use these tests on windows, but I had a look in these tests, I didn't found any test which could hit the function we are modifying. I m still working on testing this patch. If anyone has Idea please suggest.
