Run "locale" to see what locale you are running in:

$ echo foo | env LANG='C' /usr/gnu/bin/grep '[A-Z]'
$ echo foo | env LANG='en_US.UTF-8' /usr/gnu/bin/grep '[A-Z]'

The Solaris UTF-8 locales use case insensitive ordering, so [A-Z]
expands to A, a, B, b, C, c, ... Y, y, Z.

The C locale uses ASCII value ordering, so [A-Z] expands to
A, B, C, ... Y, Z.
