I apologize for my ignorance, but I don't see how that reinvents the
wheel. The function you point to would allow me to replace the
offending character if I knew what it was, but I don't know what it
is.That's why I'm walking through the string one character at a time,
checking its ASCII number. Yet even that isn't working. I can't figure
out why. But that's the question.
