FWIW: The vim poc has been "fixed" as of https://github.com/vim/vim/releases/tag/v8.0.1587
I'm just gonna go out on a limb here, and say this is an unfounded assertion. Perhaps the correct solution would be to prevent the browser from copying invisible characters. If you're going to break some basic mechanic of human computer interaction, at least don't break my damn terminal (not that I use VTE, it doesn't support OSC 52, among others), but the principle stands... Instead of worrying about sanitizing what is pasted, why not worry about sanitizing what is copied instead?
That was also the conclusion on the vim-dev list. There is a similar Debian bug report against rxvt-unicode where the same conclusion is drawn: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=787628#15 And the corresponding mozilla/firefox bug: https://bugzilla.mozilla.org/show_bug.cgi?id=637895 Best, Christian
