For instance, on HP-UX 10.20, in the en_US.iso88591 locale:

As you can see, the two en_US.iso88591 implementations are not the same.

Great!...
So which is correct?
Anyone wanting to reference an upper or lower case range
[a-z] or [A-Z], is gonna hurt from this.
Use the correct references: [:upper:] and [:lower:] or (as I do)
always use LC_ALL=C in your scripts.
My OS uses "en_US.UTF-8".
My OS uses whatever I tell it to (which is C).
You'd think unicode would have something to say about collation
order that wouldn't allow such randomness, but maybe not.
