Enhance auto complete search for special characters (eg.: pt-br accents) 

The auto complete search feature does not matches words containing special characters. This maybe not be an issue in English language, but in portuguese we have special charactars for accents, like eg.: ç in Autorização (Authorization) or "ê"in Experiência (Experience).

So It would be great to extend the lower case funcionality to tackle such cases.
