Accents Problem

Hello,

In portuguese lenguage (Brazil and Portugal), we have accents (Like these: áéíúãõôûâàèí) and when I try to write it into a chat, sign, anvil, etc., nothing happens...

On Mac OS, the keybord keys sequence for

• "á" for example is: Option (Alt) + e + a;
• "é" is: Option (Alt) + e + e;
• "ú" is Option (Alt) + e + u;

• "â" is: Option (Alt) + i + a;
• "ô" is: Option (Alt) + i + o;

• "ã" is Option (Alt) + n + a;

I hope you can solve it soon as possible. Thank you so much.
