in thread unpacking wmic command's unicode output

That's a good idea and I may resort to that. I had it in my head to get this piped from the output. Can I open a pipe as UTF-16?

Update: I was thinking of a syntax like:
wmic process | find /i "myprog.exe" | getmyfields.pl


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

      I don't get the -CS. Does wmic really output UTF-8? Wouldn't it be more appropriate to use wmic process | perl script.pl?
        Does wmic really output UTF-8?

        It appears it does (some form of unicode anyway), if you redirect its output to a file (or via a pipe):

        c:\test>wmic.exe process > junk c:\test>u:head -c 200 junk  ■C a p t i o n C o m m a n d L i n +e

        That first spludge(*) is the LE BOM 0xfffe. (It was a spludge when I c&p'd it!)

        Probably utf-16le I think, but whatever it is, using -CS does seem to cause perl to work out what it is getting and treat it appropriately:

        c:\test>wmic.exe process | perl -CS -pe1 > junk c:\test>u:head -c 200 junk Caption CommandLine

        Whether by accident or design, it is useful.


        Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
        "Science is about questioning the status quo. Questioning authority".
        In the absence of evidence, opinion is indistinguishable from prejudice.

      So it DOES! Thank you, thank you, O sage. I'd have been weeks in perlpacktut were it not for this elegant solution!
