findstr or grep that autodetects chararacter encoding (UTF-16)

Question

I want to do this:

 findstr /s /c:some-symbol *

or the grep equivalent

 grep -R some-symbol *

but I need the utility to autodetect files encoded in UTF-16 (and friends) and search them appropriately. My files even have the byte-ordering mark FFEE in them so I'm not even looking for heroic autodetection.

Any suggestions?

Answer 1

findstr /s /c:some-symbol *

can be replaced with the following character encoding aware command:

for /r %f in (*) do @find /i /n "some-symbol" "%f"
