Bash's bracket expression range expressions use the collating sequence,
as Posix specifies (though Posix limits its definition to the Posix
locale), so any locale that collates like aAbBcC...zZ will pick up
upper and lower case characters.
There is a shell option that allows you to control the behavior.
