Perhaps this is what you are looking for?

It seems to me that abs() (i.e., absolute value) is a function that
would apply to numbers, not strings. Why not write your code to use
toascii and then provide a simple wrapper function if you have to run
your code in an environment that doesn't provide a suitable toascii
