On which text editor is it easiest to prevent and/or eliminate watermarking?
Pre-installed malware that defeats anonymity being used on an airgapped system can be made ineffective, at least partially, by making sure the device does not have any of the hardware necessary to connect to the internet.
But what about watermarking? One would have to eliminate the metacontent of any traffic you want to send in a text file, and then look at it closely in hex editor.
Is there an easier way to make sure that a file has not been watermarked? On which text editor is this easiest?
