Can you try to use FINDSTR from command line (it work from eshell) and
tell me if that work on your utf-16 files?
(It seem this command is not part of powershell)

I wrote some code that use this command with success on windows (with
anything).

That would allow to have a decent grep that work on windows without
having to install external programs.

Even if that seem not powerfull as grep for regexps, that provide a
default grep command better than "grep command not found".
