How do I replace or find non-printable characters in vim regex?

Question

I have a file with some non-printable characters that come up as ^C or ^B, I want to find and replace those characters, how do I go about doing that?

Answer 1

None of the answers here using Vim's control characters worked for me. I had to enter a unicode range.

:%s/[\x00-\x08\x0B\x0C\x0E-\x1F\x7F-\x9F]//g

That unicode range was found on this other post: https://stackoverflow.com/a/8171868/231914
