merge r9819 from branch 2.1 to trunk

bug 2228 fixed: there should be no blank space in the URL to avoid infinite
loop redirection (this happens with chinese only characters + blank space in
the category name).

Note: this problem does not concern tag names because there is no redirection
when the tag name does not match tags.url_name
