Yes, and then there is locale: does [a-z] include ij when you run it
in Holland (it should)? Does it include á, è, ô in France (it should)?
Does it include ø, å in Norway (it should not)? And what happens when
you evaluate "è" < "o" (it depends)?
Fixing awk is much harder than anyone things. I had a chat about it with
Brian Kernighan and he says he's been thinking about fixing awk for a
long time, but that it really is a hard problem.
