^@ is the null char and Eli just showed you how to search for it.

Similarly, C-s C-q C-h will search for a ^H char.

Assuming \342\200\230 is three octal characters then, I would probably
resort to editing the search string and using `insert-char':

C-s M-e
C-x 8 RET #o342 RET
etc...

If you can *see* an instance of the character already, you might just
move point to that character and use C-s C-w (and maybe a bit of C-M-w
if that grabs too many chars).

Or if you mean "any non-ascii character" then the regexp [^[:ascii:]]
will match those.
