typo Live Search

Typo, the Ruby-based blog engine that I am using, has a cool "Live Search" feature (i.e. search as you type by using Ajax). However, it doesn't work with multibyte characters. I fixed it with modifying the Javascript from "escape($F('q'))" to "encodeURIComponent($F('q'))"... Then when trying to submit it through Trac, I found it has already been submitted :P
