Tags written in Japanese are silently lost on the openclipart.org setup of cc-host.
To reproduce:
Go to openclipart.org
Upload clipart
Enter Japanese text as a tag (either from IME or pasted from here : これはタグです。It says "this is a tag")
Actual results
The tag doesn't appear in the list of tags for the clipart, nor in the page for browsing tags.
Expected: Japanese text treated the same as English text.
This probably affects other languages, but I can't test that so easily here. Japanese text can be entered to other parts of the site, for example in descriptions.

This is part of the hunt and fixing of multibyte language code issues in cchost.
