That's a good point. Well... In between responses, I was excited to stumble upon a possible silver bullet. There is a "disableAnsi" attribute on the pattern layout [1]. Trying it on my file appenders, I can say most of my log files are now without ANSI escape codes. That's good!
However, I still got a few. It's an oddity and possible edge case. If the message (%m) includes ANSI escape codes, those are passed right through. So I guess "disableAnsi" is only a filter for the layout "pattern" and not the message itself? And what do you guys think of this behavior?
