[3.7] bpo-29571: Fix test_re.test_locale_flag() by vstinner · Pull Request #12178 · python/cpython (original) (raw)
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().
