Problem: Readers using languages that have variants find it inconvenient to read translatable pages (in meta, MediaWiki, wikidata, commons, etc.). The link Special:MyLanguage redirects to the translated page with the users system language. However, take an example of Chinese, the system language of users (defined in Special:Preferences) is often one of the variants of Chinese, for example, Mainland China Simplified Chinese (zh-cn), Taiwan Traditional Chinese (zh-tw), Singapore Simplified Chinese (zh-sg) etc. Translatable pages may have "/zh" subpage, but no "/zh-cn", "/zh-tw", "/zh-sg" subpages, so Special:MyLanguage redirects to the original English page. Page "/zh" may exist (which supports language converter), however Special:MyLanguage does not redirect to it, unless the user's system language is exactly "zh" instead of "zh-cn", "zh-tw", "zh-sg". In case our system language is exactly "zh", the Special:MyLanguage can redirect to "/zh", but not the converted version. Actually, users using Chinese prefer to read Chinese pages converted to their variant, instead of the "unconverted" original Chinese. Btw, in this page, the button content that uses {{zh other}} and {{dynamite}} to display my language is also unconverted, as the page lang of this page is not "zh". I hope it can fix too.
Proposed solution: For example, if my system language is "zh-cn", the Special:MyLanguage should redirect to the "/zh" translation of page with parameter "?variant=zh-cn".
Who would benefit: Users using languages that support language variants.
More comments: This issue has been talked about many times in Phab, yet with few solution. I hope the issue can fix through this wishlist survey.
