Well Backspace for sure, maybe Tab (if it's inserted in an edit
control, don't know if that's possible), same doubt about newlines
('\n' and '\r') or "vertical tab" (are those valid in certain edit
controls?).

I mean if anything '\b' has to be an exception, at the very least. The
rest can be ignored I guess, if you want to simplify this to just one
check for '\b' instead. Should I just check for backspace?
