Hi,

I am using wordpress with this type of permalink:

/%year%/%monthnum%/%postname%/

if I use this type of url: example.com/2010/03/?????

it treats this url like this example.com/2010/03/ (By ignoring unicode chars) and displays March 2010 archive list.

if I use english url: example.com/2010/03/technology then it works perfectly.

This problem occurs even on tags page: for example example.com/tag/??????? is treated like example.com/tag/ and displays 404 page.

Why wordpress is ignoring unicode chars?

If I use default querystring structure then it works perfectly even with unicode characters.
