I have some logs which I want to read in less. Unfortunately, scattered throughout the otherwise text file are some non-ascii characters that less displays as highlighted junk. This is really annoying.

How do I get rid of the highlighting?

There doesn't appear to be an option for it. Your choices then are (a) build your own modified version of less, and (b) filter those characters out before less gets hold of them, like this:

LANG= tr -cd '[:print:]' <yourfile | less

LANG is unset so that tr doesn't try to combine control characters into multibyte characters.

Or use:

less -r

(display raw characters, if your terminal supports that)
