        Actually it makes sense that it would... and it DOES.

Bash and POSIX would appear to violate Unicode ordering.

Algorithm reference: http://www.unicode.org/reports/tr10/tr10-24.html

Collation order chart:

It shows that cap A-Z come before a-z.

If a sort order is set (as mine used to be) to
en_US.UTF-8

then the Unicode sort order should have been used.

In bash, it was not.

It sounds like this is a bug rooted in the C libraries?
