I'm not sure about this but try increasing the size of the letter variable to 2, because if I remember correctly, it requires an additional cell to store the end of string specifier.

If you need to save a single character, use the 'c' specifier. Strings always need a NULL terminator and therefor always have to be at least 2 cells big.
