While browsing in my Special:Preferences today, I noticed that we apparently support no less than five variants of Chinese:
zh zh-cn (simplified, as used by the Chinese mainland) zh-hk (traditional) zh-sg (simplified) zh-tw (traditional)
In translating the Commons namespace pages and templates, we seem to most commonly have zh-hans and zh-hant, corresponding to simplified and traditional characters. I think the "han" is to qualify the language as Mandarin (also known as Hanyu, literally the language of the Hans) rather than, say, Cantonese (zh-yue) or any other variety of Chinese. I have noticed that people seem to have stopped using zh-tw and zh-cn. Which makes sense: the country distinction is not what's important in this choice. AFAIK there are no major differences between Chinese as written in mainland China and Singapore, so I don't know why we offer that distinction.
I don't even know why we still have people doing the man-hours of 'translating' between traditional and simplified when zh.wp is, after all, using some automatic converter. Should we ask for it to be installed for Commons? I don't know why it wasn't in the first place... I have a small suspicion that the traditional folks enjoy maintaining their translations, why is why no one's raised the issue, but it's just a hunch.
Any thoughts?
