Don't know about "sed" on Windows, but that would be highly unusual for Perl on Windows:

"vis" is just a small C program that makes non-printable characters visible in octal code.

Hello,
Yesterday I was looking for a way to grep for a tab in the shell, and found this solution in several places:
grep $'a' # Grep for the letter 'a' between two tabs
