[3.7] bpo-29571: Fix test_re.test_locale_flag() (GH-12178)
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().
