In this case, with diamonds being displayed instead of escape sequences. But that also applies to anything, so there is nothing to define here.

I don't see why you have to conflate clearly unreasonable "comfort" with reasonable behavior, such as letting the Linux console display undisplayable characters as diamonds.
