Not to mention octal character  \201 which is interpolated quite silently:

c:\@Work\Perl\monks>perl -wMstrict -le
"my $fn = qq{E:\Music\Ray LaMontagne\2010 - God Willin' & The Creek Do
+n't Rise};
 print qq{'$fn'};
"
Unrecognized escape \M passed through at -e line 1.
Unrecognized escape \R passed through at -e line 1.
'E:MusicRay LaMontagneü0 - God Willin' & The Creek Don't Rise'
