jQuery UI Autocomplete for Japanese IME

gistfile1.js

// jQuery UI doesn't work with Japanese, Chinese and probably other
// languages' IMEs.
//
// This code snippet is a modified code of jQuery UI Autocomplete 1.8.16
// that works with Japanese IME. It's based on the code in the ticket below.
// http://bugs.jqueryui.com/ticket/5933
// 
// I briefly tested it, and it seems ok.
// Any comments/feedback would be appreciated.
