Thread:Talk:Requests for comment/API Future/What is converttitles?/reply

It's for the language converter, which automatically converts between language variants (Used mainly in Chinese and serbian - serbian is a lot easier for testing as the variants are latin and cryllic which are much more identifiable to an english speaker than simplified chinese vs traditional chinese)

Note: it's not exactly a "normalization" as users can create pages in both variants, and I don't think one variant is considered more "correct" than the other (don't quote me on that). I think there are cases where you wouldn't want to convert titles, but am unsure.
