Regarding this message:

Figure out what file handle is being printed to at line 122 of that script. If it's STDOUT, then somewhere before you reach that statement, you should do:

binmode STDOUT, ':utf8';

If it's some file handle that you open, add ':utf8' to the mode portion of the open call - e.g.

open( my $output_handle, '>:utf8', $output_name ) or die $!;
