Nokia :: Circumflex / Tilde And Other Characters Not Working

I cannot type in the circumflex and tilde characters (as well as some others). When using the hardware keyboard, I use the Sym key to get the onscreen selection of symbols/chars and from there, all the characters work except for all those on the row that contains the circumflex and tilde. I also tried enabling the onscreen keyboard and selecting them from there, but they don't work in that either. When touching the tilde button, it turns orange, but does not transfer the character into the text area like it does with the less than character for example.Does anyone know how to get that working please?
