$ perl -e " print chr(999) " Wide character in print at -e line 1. ╧ $ perl -e " binmode STDOUT; print chr(999) " Wide character in print at -e line 1. ╧ $ perl -Mdiagnostics -e " print chr(999) " Wide character in print at -e line 1 (#1) (S utf8) Perl met a wide character (>255) when it wasn't expecting one. This warning is by default on for I/O (like print). The eas +iest way to quiet this warning is simply to add the :utf8 layer to the output, e.g. binmode STDOUT, ':utf8'. Another way to turn off the warning is to add no warnings 'utf8'; but that is often closer to cheating. In general, you are supposed to explicitly mark the filehandle with an encoding, see open and perlfunc/binmode. ╧
So to silence the warning, use
$ perl -e " no warnings q[utf8]; print chr(999) " ╧
using bytes would also silence it, but would change the semantics
$ perl -e " use bytes; print chr(999) " τ
