Sorry for the delay in replying. You problem is caused by an interaction
between the way Perl 5.8.0 handles UT8 locales, and the fact that Redhat 9
enables UTF8 locales by default.
Because you have this environment variable set to something including
UTF-8,
> LANG=en_US.UTF-8
Perl 5.8.0 by default does its output in UTF8. The two solutions are
either to upgrade to Perl 5.8.1, or to remove UFT8 from any locale
environment variables.
