How to find base character from an accented character

Hi, given an accented character (? ? ? etc...) is there a way to retrieve its base character? In the case above, a, o and c respectivelly?

I searched in this forum and google and didn't find a definitive answer.

The reason i need this is because in my database, some records have accented content, and now i need to generate a textfile to transfer daily to a bank, but the bank doesn't accept accented characters.

Thanks.
