404 issue with different languages

Hi,

Thanks for the plugin.
It seems that it creates and issue when using non-latin characters (specifically Thai and Japanese in my case) in the URL.
When clicked on the category as a link within the site you get it, however if refreshed or if going directly to that URL there is a 404 message.

I’ve seen this issue in the forum before but couldn’t solve it.

Please assist.

Thanks
