in reply to Bug in perl -C (Unicode) option parsing?

It's not system-specific. I can replicate your results in Windows. 

>perl -l -CDS -e "print qq{\x{101}}"
[funky chars]

>perl -CDS test-noCDS.pl
[funky chars]

>perl test-withCDS.pl
Wide character in print at test-withCDS.pl line 2.
[funky chars]

This is perl, v5.8.8 built for MSWin32-x86-multi-thread
Binary build 817 [257965] provided by ActiveState
Built Mar 20 2006 17:54:25

The fourth test has a different result, because it's the same as the third test in Windows. 

>test-withCDS.pl
Wide character in print at test-withCDS.pl line 2.
[funky chars]

Could it be related to the script starting execution before the -CDS switch is encountered? In other words, maybe STDIN, STDOUT, STDERR have already been created by the time shebang -CDS is encountered.

    It seems ikegami (and my unstated suspicion) were correct. Bleadperl now dies:

    perl-5.9.4-build$ ./perl test-CDS.pl
Too late for "-CDS" option at test-CDS.pl line 1.

    I thought the error looked familiar, so I tried it with "-T", but I see that one is now updated to:

    perl-5.9.4-build$ ./perl test-T.pl
"-T" is on the #! line, it must also be used on the command line at te
+st-CDS.pl line 1.

    (With perl5.6.0 and perl5.005_03, I get the familiar:)

    old-solaris-machine$ perl5.6.0 test-T.pl
Too late for "-T" option at test.pl line 1.

    So, it seems it was a bug, but it's been fixed in the 5.9 line.
