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

You can use:

:%s/^C//g

To get the ^C hold the control key, press V then C (Both while holding the control key) and the ^C will appear. This will find all occurrences and replace them with nothing.

To remove both ^C and ^B you can do:

:%s/^C\|^B//g
