+Subject: [PATCH] i18n: Blind fix attempt for std::bad_cast being thrown on
+ Windows
+
+Several reports on Steam and our forums point at std::bad_cast being
+thrown when accessing Preferences and the Multiplayer menu amongst
+others. It's possible that the locale configuration on those systems is
+not quite right, and compare() and icompare() are able to throw
+std::bad_cast when this happens as they both use std::use_facet().
+
+Note that much like the macOS/iOS version of icompare(), this stopgap
+patch doesn't attempt to provide any form of case-insensitive fallback
+and just uses a case-sensitive comparison instead.
