// FIXME for lowercase() and uppercase() function below:
// 1) std::tolower() and std::toupper() are templates that
// compile fine with char_type. With the test (c >= 256) we
// do not trust these function to do the right thing with
// unicode char.
// 2) these functions use the current locale, which is wrong
// if it is not latin1 based (latin1 is a subset of UCS4).
