ZenRep is awesome! I'm using it in my brazilian service and it works pretty well.

However, the pt-br URL paths has accented characters which breaks in some international browsers.

Take as example the idea: "Faça alguma coisa incrível no site!" ("Do something amazing in the site!" in pt-br), there are special characters that must be transliterated to normalized ones, like the "ç" that must become "c", and the accented "í" that must be "i". It helps to keep URLs uniformed in many places like email clients, social networks and so on.
