23005	Improve zh-* language code handling	caxekis@…	nobody	"As per #18419, zh-cn and zh-tw are deprecated and one of the reason was that ""...Traditional Chinese is not used only by Taiwan (tw) but also Honk Kong (hk), and Simplified Chinese is not only used in China (cn) but also Singapore (sg) and Malaysia..."" . However pull #1868 https://github.com/django/django/pull/1868 did not specify fallback for those language variant.

I would say we should follow Mediawiki's configuration for chinese language variants fallback (see https://git.wikimedia.org/blob/mediawiki%2Fcore.git/e016f6aa9386f515398d07d25419650c1fb74bf6/languages%2Fclasses%2FLanguageZh.php#L104 line 104 ).
* zh-cn, zh-sg and zh-my fallback to zh-hans
* zh-hk, zh-mo and zh-tw fallback to zh-hant"	Bug	closed	Internationalization	dev	Normal	fixed	i18n, chinese, zh		Ready for checkin	1	0	0	0	0	0
