A terminal that can handle UTF-8.
You may need to put this in your profile
#fix UTF-8 support
export LC_CTYPE=en_US.UTF-8 #vim needs this to swtich it from Latin1 to UTF-8
export PERL_UNICODE=SDL #Makes Perl use UTF-8 for IO
You might also need the right fonts. Try this instead (I think
CIRCLED DIGIT ONE is more commonly supported):
perl -le 'print "\x{2460}"'
