wordpress - Collation urls not followed for Google Webmaster -

I have not followed the page on Google Webmaster I check them and that's because the exact URL

I try to follow the title of "x" on it and when I post only a strange% C3% 97 like a new serial episode like this title: Burn Notice 7x02 SubSpea ± Oll online. When the number% C3% 97 appears between X and it duplicates my post

That's why I try to recover from changing the database compilation from 1_swedish_ci to utf8_general_ci but it still has the same header. I check my wp-config.php as well and define it ('DB_forerty', 'UTF8');

Please do some body know any good solution to fix this situation?

Thank you in advance

You say that Google is using :

  http://www.mysite.net/2013/06/burn-notice-7%C3%9702 -sub-espanol-online.html   
 Almost similar to the URL:  
  http://www.mysite.net/2013/06/burn-notice-7x02-sub-espanol-online.html   
 As percentage encoded characters actually aka aka it's a 'one'? Not an 'X' Google is simply using a secure encoded version. It means that your database is fine, because it is showing ULL as valid UTF8.  
 The problem is that you are interpreting the requested URL and trying to match it with the database. PHP should already decode the percent encoded value for 'A', either:  
 
 
 is breaking some strings (eg Strtolower such as non-multibyte safe The function is calling) instead of Mb_strtolower ().   
 
 Your PHP code is connecting to a character set other than UTF 8 from the database, please check that the 'default-character -set = utf8' in your my.cnf file In the 'Client section'    
 Or any other issue is valid though the URL is.
