Sorry, something went wrong.
Use locale.getpreferredencoding() rather than locale.getlocale() to get the locale encoding. With some locales, locale.getlocale() returns the wrong encoding. For example, on Fedora 29, locale.getlocale() returns ISO-8859-1 encoding for the "en_IN" locale, whereas locale.getpreferredencoding() reports the correct encoding: UTF-8. On Windows, set temporarily the LC_CTYPE locale to the user preferred encoding to ensure that it uses the ANSI code page, to be consistent with locale.getpreferredencoding().

I tested manually the PR on Linux with "LANG=en_IN ./python -m test -v test_re": fail without the change, pass with the change. I also tested the PR on Windows: test_re pass. |
