The result of [a-z] in locales other than C or POSIX is implementation-
defined.  If you want to refer to "any lower case letter" portably,
you need to use [[:lower:]] instead.

However, bash does define a shopt called "globasciiranges" which
changes the behavior of [a-z] from locale-based to traditional US-ASCII.
You might want to try that, if you aren't willing to use the portable
syntax, or to dumb down your LC_* variables.
