Both flat files and MySQL with the tables specifically set to utf8.

I was thinking I might need to get the "process" in View::TT
changed to something more like this:
   unless ( $self->template->process( $template, $vars, \$output, 
binmode => ':utf8' ) ) {
But I just tried that and it also made no difference. So, I think you're
right the incoming data is squirrelly.

I just checked and it looks quite different from some of my others in 
so something happened with that file... "??"s everywhere instead of
nice "\302\267"s.

Thanks, I will. I understand the concepts but haven't tried to hack
with it before.
