in thread unpacking wmic command's unicode output

Now I'm confused. a) how would it hurt? b) Why does it seem not to hurt in my use now?


#my sig used to say 'I humbly seek wisdom. '. Now it says:
use strict;
use warnings;
I humbly seek wisdom.

    how would it hurt?

    >perl -e"print qq{C\x00a\x00p\x00}" | perl -CS -we"print length <>" 6

    Why does it seem not to hurt in my use now?

    Because -CS has no effect if there are no bytes with bit 7 set.

      but that's not -CS's fault, as it prints 6 without -CS as well. Or am I missing something still?


      #my sig used to say 'I humbly seek wisdom. '. Now it says:
      use strict;
      use warnings;
      I humbly seek wisdom.

        Ok, I'll cede that while it has an effect (data from STDIN should be considered decoded), saying it's harmful is incorrect.

        However, it doesn't fix the problem it's suppose to fix. As a solution, it's useless and therefore wrong.
