correct. More specifically, the output is - I think - utf-16 (or was it
UCS-2?)
but instead of leaving the null bytes alone, Vim converts those to SOH
(0x01).
That's why you see all those ^A characters there (plus the BOM in the
beginning
of the string, so you can't even convert it on the fly using iconv() or
such).

I think Vim should try to convert the output of the system command.
There is an entry in the todo list about it.

A simple work around is, to pipe the output through findstr. So this
should work:

:echo system("wmic logicaldisk get deviceid|findstr '.*'")

Alternatively, you might be able to script something using systemlist()
and iconv()

Best,
Christian
