I'm inclined to suggest the regex compiler should issue a warning for
this.
I've never seen a character range other than A-Z, a-z, or 0-9. Well, I
suppose A-F or a-f if you're trying to match hex digits (and some
variations on that for octal). But, I can't imagine any example where
somebody wrote A-z and it wasn't an error.
