The only involvement of Unicode is the use of UTF-8 when you provided invalid data to print

Utter twaddle!

The unicrap 'manifests' regardless of whether you call print:

C:\test>perl -MDevel::Peek -E"$x = '--*--'; substr($x,2,1) = chr(~0); +Dump( $x )" SV = PVMG(0x250e68) at 0x2669c8 REFCNT = 2 FLAGS = (SMG,POK,pPOK,UTF8) IV = 0 NV = 0 PV = 0x252e48 "--\377\200\217\277\277\277\277\277\277\277\277\277\27 +7--"\0 [UTF8 "--\x{ffffffffffffffff}--"] CUR = 17 LEN = 24 MAGIC = 0x2b66a8 MG_VIRTUAL = &PL_vtbl_utf8 MG_TYPE = PERL_MAGIC_utf8(w) MG_LEN = -1

Perl has silently and unwantedly f***** my data. Broken!
