in thread unpacking wmic command's unicode output

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.

        As a solution, it's useless and therefore wrong.

        Hm. That's a bit strong. As a solution, it produces the desired result. Ie. The data in the file is sans unicoding.

        The fact that the -CS isn't actually responsible for that--nor even perl itself directly--doesn't detract from the usability of the solution to produce desired result.

        As it turns out, wmic process | perl -pe1 > file also produces the desired result, and as its 3 characters shorter I guess that makes it a superiour solution. I would have suggested that; had I thought to have tried it.

        It turns out that it just going via a pipe that causes wmic.exe to produce ansi output rather than unicode, so a simple wmic process | tee > file works.

        And it's even shorter.
