Description of problem:
Hi,
  Bash doesn't seem to be expanding regexps as I would expect (csh and
ash do not exhibit this problem).  With LANG set to en_US.UTF-8, "ls
[A-C]*" is NOT the same as "ls [ABC]*".  The first ls returns lower
case b and c files while the second does not.  If I change LANG to be
"C", it works as I would expect it to (both ls's return the same output).


Version-Release number of selected component (if applicable):
bash-2.05b-38

How reproducible:
Always

Steps to Reproduce:
1. mkdir /tmp/fubar && cd /tmp/fubar && touch a1 b1 c1 d1 A1 B1 C1 D1
2. export LANG=en_US.UTF-8
3. ls [A-C]*


Actual Results:  A b B c C

Expected Results:  A B C

(Slight terminology correction: these are not regexps but pathname expansion
patterns.)

The behaviour you see is intentional.  See the bash FAQ, question E9:

Sorry to waste your time -- thanks for the pointer.
