I can't reproduce your problem.

this works for me: 

$ perl -d -e'binmode DB::OUT,":utf8"'

Loading DB routines from perl5db.pl version 1.28
Editor support available.

Enter h or `h h' for help, or `man perldebug' for more help.

main::(-e:1):   binmode DB::OUT,":utf8"
  DB<1> 

  DB<1> s
Debugged program terminated.  Use q to quit or R to restart,
  use o inhibit_exit to avoid stopping after program termination,
  h q, h R or h o to get additional info.  
  DB<1>  p "\x{224}"

(I had to put the printed char outside of the code tags because perlmonk's code mangles it otherwise)

update: note that if the binmode() part of the code hasn't (yet) been executed, I get the usual error messages: 

  DB<1> p "\x{224}"

Update 2:

You should be using binmode DB::OUT,":utf8" instead of binmode $DB::OUT,":utf8"
