Yeah it's probably fine to close.
FWIW, I have code on top of my encoding PRs for opening binary files, but that's limited to the loading and encoding management, not adapting all code to work with NULs. Yet, search seems to work fairly well @elextr 😉 Anyway, I'm not sure we're gonna merge it, as it's not 100% trivial and doesn't necessarily add a lot of value if most features are half-broken -- however it could help with viewing broken log files or fixing a tiny corruption.
