Install Devel::Unicode then run your script like this:

perl -d:Unicode yourscript.pl

[download]

... and magically all data printed to STDOUT will be passed through a Unicode debugger allowing you to see all the interesting characters more clearly.

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
