Is it really a programmer mistake, though, to assume that [A-Z] is only
capital letters? A through Z are a contiguous range in every
representation system except EBCDIC, and it is even contiguous the
modern unicode.
In the world of programming characters are numbers, and programmers know

This is a thorny issue that plagues all POSIX-compliant utilities,
not just Bash. (POSIX locales are just a blight.)
For gawk 4.0, I have said "to heck with it" and changed gawk so that
ranges act like they are in the C locale (unless --posix is used).
I and some other people are campaigning to

Oh, look, there's more!

Right; forgot about ls (because "alias ls='LC_COLLATE=C ls'" has been in
my .bashrc for so long that I completely forgot it was there :) ), and

If you ever want a subset of [[:upper:]], the _
