How to properly pass address to google geocoding service

Programmer Question

I'm getting some problems trying Google Geocoding service when using special characters like "�" or letters with accents.

Whenever I try something like:
"barcelona, n� 10"

I get 0 results. But trying:
"barcelona n 10"

I get results...

I suspect is something related with encoding.
I tried this:

geocoder.geocode({'address': encodeURI( $('#direction').val() )}, function(){} );

But didn't help.

Any Idea?
