Drupal Community Portal

Hello,
I've been searching info but can't solve this.
I've many buttons with an image associated to each as link background. My website is in English and Spanish, and link classes come from link's title. So...
Views generates classes from node titles, so it's giving me "Revalorización" as class, and CSS file can't get it because of the accent.
I've installed Trasnliteration, but it doesn't seems to affect.
Do you have some info or ideas?
