From a1c27748d22f94d608cc499db527bf989a5516f2 Mon Sep 17 00:00:00 2001 From: Edward Welbourne Date: Thu, 2 Mar 2017 14:23:05 +0100 Subject: [PATCH] Make QLocale consistent about special handling of the C locale QLocale::matchingLocales() simply created each locale using the basic data, without (unless the matching conditions stipulated Language C) applying number-options hacks that it applies everywhere else, when creating the C locale. Thus the C locale in its returned list (if it wasn't the only entry) ended up with the default number options, without omiting separators in numbers. Thus QLocale::c() didn't actually appear as an entry in the list. Discovered while investigating QTBUG-58947. Added a dumb autotest that checks various ways of getting the C locale do actually give us equal locale objects. Fixed matchingLocales() to apply the same hack as is used elsewhere for the C locale.
