If I run this script: #!/usr/bin/perl use open IN => ":byte"; use constant A => 1;
on a MacBook Pro (Intel) With perl version 5.8.6 (the pre-installed) I get this error: Can't locate constant.pm in @INC (@INC contains: /sw/lib/perl5 /sw/lib/perl5/darwin /System/Library/Perl/5.8.6/darwin-thread-multi-2level /System/Library/Perl/5.8.6 /Library/Perl/5.8.6/darwin-thread-multi-2level /Library/Perl/5.8.6 /Library/Perl /Network/Library/Perl/5.8.6/darwin-thread-multi-2level /Network/Library/Perl/5.8.6 /Network/Library/Perl /System/Library/Perl/Extras/5.8.6/darwin-thread-multi-2level /System/Library/Perl/Extras/5.8.6 /Library/Perl/5.8.1 .) at ./tst.pl line 3. if I change the line to: use open IN => ":encoding(UTF16-BE)"; I get this error: Unrecognized character \xE0 at /System/Library/Perl/5.8.6/constant.pm line 1. In both cases: If I swap the lines, everything runs smoothly. Anyone seen this behaviour? What to do about it?
