Hello. :)

I wanted to ask.. Is it possible to get the latvian keyboard layot (with latvian characters) or add missing characters to the english keyboard layoot for my w890i?

Because I have the latvian interface but I can't write sms in my own language.
The missing letters to the english layot are:
ē, Ē, Ū, ū, ī, Ī, ā, Ā, š, Š, ķ, Ķ, ļ, Ļ, *, Ž, č, Č. ņ, Ņ.

Is it possible to add them to the english character table?

Would appreciate help. :)
