if tag slug contains chinese letters – appears 404

if tag slug contains chinese letters – appears 404 too.

If open archive of this tag by link from admin panel/tags – archive opens. But if you open URL from another place – display 404 error too.

———–
And,if deactivate the plugin,it is not show 404 .(‘/tag/’+chinese letters can work)

Thanks very much!!!
