Accented words

I'm running a radius server with multiple eap modules, depending on the CommonName will be redirected to one or another module, the CommonName is like this: "<APELLIDO>, <NOMBRE> (AUTENTICACIÓN)," the problem is that it seems that FR does not recognize the accented literal "AUTENTICACIÓN". The log says "Evaluating (User-Name == "<APELLIDO>, <NOMBRE> (AUTENTICACI") -> FALSE". Any idea how to fix it?
