That this works in any locale in Linux a GNUism, you cannot rely
on the portability of such a contruct in anything but the POSIX
locale (see also
http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html#tag_09_03_05)
because ranges inside bracket expressions depend on the order of
characters in a locale.  If you want it to work the way you
expected it to work set LC_ALL=C or LC_COLLATE=C.
