While I agree what you're saying philosophically here, I suspect you'd
still need another attribute for "no really, this needs to be checked
out as encoding X". The same way we treat line endings as a platform
decision, but we still need to have `eol=crlf` for those files which
really, no matter what platform you're on, have external tools depending
on them to have some particular line ending.
So a full proposal would support both cases: "check this out in the
local platform's preferred encoding" and "always check this out in
_this_ encoding". And Lars's proposal is just the second half of that.
But I'm not sure anybody even really cares about the first part; I don't
think we've seen anybody actually ask for it.
