This seems to be a totally undocumented area of the MediaWiki codebase. Nothing on mw.org; precious little in code comments. What is LanguageConverter.php, when is it called, what does it do? How does the new (as of r48984) parser function {{GROUPCONVERT:...}} fit in?
The closest thing to documentation that I've been able to find, in English at least, is <http://meta.wikimedia.org/wiki/Automatic_conversion_between_simplified_and_traditional_Chinese>. It's not very useful for developers interested in learning how the system works, though. I suspect there may be more documentation in Chinese somewhere on zh.wikipedia, but if so, I don't know where and it wouldn't be of any use to me anyway since I can't read Chinese.
FYI: * {{GROUPCONVERT:...}} was removed in r51405 * There is more information about the conversion system at ** http://zh.wikipedia.org/wiki/Help:%E5%AD%97%E8%AF%8D%E8%BD%AC%E6%8D%A2%E8%AF%AD%E6%B3%95 ** http://zh.wikipedia.org/wiki/Help:%E4%B8%AD%E6%96%87%E7%BB%B4%E5%9F%BA%E7%99%BE%E7%A7%91%E7%9A%84%E7%B9%81%E7%AE%80%E3%80%81%E5%9C%B0%E5%8C%BA%E8%AF%8D%E5%A4%84%E7%90%86 (It is more or less readable using a translator) Helder
I started a page at <http://www.mediawiki.org/wiki/Writing_systems>.
more documentation of the LanguageConverter and variants would be super helpful. :) right now I need to look at the code, ask certain people or make a guess as to why things are done the way they are.
