I think if you used UTF-8 as the output character set you avoid all
these problems. The conversion from UCS-2, etc. to UTF-8 is fairly
straightforward, and should be at least as quick as using %. Most
importantly it is more compact (e.g. for Japanese characters 2-3 bytes
instead of 6 bytes for %XX%XX).
