What language are we talking about? (The answer is not "Korean, you doofus, didn't I say that?" ;) ) The database itself doesn't do the work; it just stores what you give it. Different languages have different decoding commands. Sometimes more than one per language.

For comparison purposes: when I added full-spectrum percent decoding to my log-wrangling routine, which uses javascript, it turned out that you have to use one function for ASCII characters and a completely different one for the higher ranges. This makes no sense-- but there you are.

If it's any consolation, occasional visits to the in-progress areas of Google In Your Language suggest that even they haven't got it figured out yet :)
