I've not tried anything real yet, but I will soon. It might be
something trivial but it's a bit scary to think what will happen in
real-life application (eg I need to recode to UTF8 any czech chars to
make it work in Apache::ImageMagick).

See below for perl -V output. Given this is standard RedHat 8.0 RPM
Perl, as people start to upgrade, we'll see probably many more similar
complaints. Right now I don't use RH8 for more then testing, but let me
know if I can be usefull.
