Problem URL SEO

I have the following problems with the urls, eats the words with accents (accent).

Example:

http://eresdigital.com/m/tutoriales/ver/Tipograf-a-digital-con-CorelDraw-X3

 It should be

http://eresdigital.com/m/tutoriales/ver/Tipografia-digital-con-CorelDraw-X3

It happened because of non-latin character occurrence in the phrase.

But you can enable non-latin characters in permalinks by seeing to "true" the following option:

var $bAllowUnicodeInPreg = false; // allow unicode in regular expressions

in templates/base/scripts/BxBaseConfig.php file, but sometimes php doesn't support this (unicode in regular expressions), then you have to stick to the previous setting.

Thanks, it worked perfectly
