Comment(by tosak):

 If you save a page with say Kanji letters:
 http://localhost/wp/漢字

 WP saves the regex as:
 (%e6%bc%a2%e5%ad%97)(/[0-9]+)?/?$

 Then when you call the page, WP decodes the request, but not the regex, so
 it tries to match 漢字 against (%e6%bc%a2%e5%ad%97)(/[0-9]+)?/?$ resulting
 in a 404

 if you use rawurlencode, WP correctly matches 漢字 against (漢字)(/[0-9]+)?/?$

 I'm sorry if I misunderstood what we're trying to do here, this just fixed
 the issue with foreign characters in URL's and 404's for me, so wanted to
 share it.
