URL rewrite of SEC is not optimize for Google or other search engines?

I found SEC URL rewrite does not seem to optimize for search engines. As you can see in the photo, SEC show the title of the post with nonsense characters compare to another.

Please check and fix the issue. Thanks.

    Jung Kim Can you open a support ticker regarding this? I am suspecting this might be happening because of the special Vietnamese characters.
