It's a text file, but not ASCII. It's encoded as Emacs is telling you:
utf-16, with signature, in little-endian order (it starts with FF FE).

Curious. I get utf-16le-with-signature-dos, consistent with the file
having CRLF (which it does).

It is. This is unrelated to Emacs. The grep tools you're using do not
support utf-16 text.

Ah, that explains the -unix above.

I hope this is clearer now.

It will be useless whenever you try to grep a file in a coding system
the grep tool does not support...

How do we handle what? If you mean, how can Emacs read the text just
fine... Emacs has supported UTF-16 and many other coding systems for
years.
As for what can you do,
C-x <RET> f iso-latin-1-unix <RET>
then save.
