but for one reason or another, it did not produce the desired results.

It would be neat if you could show a minimal self-contained example to demonstrate this. It could be you were still missing something simple, like you did binmode STDOUT, ":utf8"; but then actually read your input from some other file handle (e.g. ARGV), instead of actually piping or redirecting data to the script. And see what the results actually were could help as well.
