If I may nitpick, "high ASCII" is not the right terminology here.  
The ASCII table only contains 128 characters, with codes 0…127 (where
only codes 32…126 have a visual representation.)

What you call "high ASCII" are Unicode characters that are autside
ASCII, or Latin-1 characters that are autside ASCII.  In both cases they
have codes greater than 127.

I usually do a :set hls (highlight search results) followed by /[^ -~]
(search for any character that is not between space and tilde, ie. that
is not a printable character from the ASCII set.)  You can add the tab
character (with Ctrl-V Tab) inside the square brackets if you use it in
your documents.  It will show as /[^ -~^I] with a blue ^I.

This has the added benefit of hitting n to get to the next one.
