Probably the same thing I ran into with LANG != C
try this little test:

$ cat t_regex
#!/bin/bash
# t_regex: Test test regex
# By Lee Rothstein, 2010-12-03, 16:27:38

regex_test () {
if [[ "$1" =~ [A-Z] ]] ; then
   echo Contains Capital Letters: $1
else
   echo Doesn\'t Contain Capital Letters: $1
fi
}

export LANG="C.UTF-8"
regex_test dfgh

export LANG="en_US.UTF-8"
regex_test dfgh


 ~/src
$ ./t_regex
Doesn't Contain Capital Letters: dfgh
Contains Capital Letters: dfgh

Welcome to the new world order :-0   I tried to figure out why the
collating sequence changes with the language settings but didn't get
anywhere beyond the fact that it _does_ change.  Oh well.. try, try
again.
