How to find non-ASCII characters in Vim

If you copy paste text from external sources into Vim, you might end up with non-ASCII characters.

To find the non-ASCII characters in the file open in Vim, try this search: /[^\x00-\x7F]

This tries to highlight all the characters that lie outside the given range, that is the ASCII range.

Tried with: Vim 7.3 and Ubuntu 12.04
