It's your locale setting.  Range expressions in pattern matching use the
current locale and its collating sequence.  See what $LANG, $LC_ALL,
$LC_COLLATE, and $LC_CTYPE are set to.

The common `en_US' locale setting collates alphabetics like

        AaBbCc...Zz

so [a-z] will match all of the lowercase letters and the uppercase
letters between B and Z.
