No, that is absolutely the wrong approach.

If someone has a local setup which makes bogus assumptions about text
encodings, that is their own mistake.

We don't do them any favours by trying to *hide* it in the common case
so that they don't notice it for longer.

There really isn't much excuse for such brokenness, this far into the
21st century.

Even *before* UTF-8 came along in the final decade of the last
millennium, it was important to know which character set a given piece
of text was encoded in.

In fact it was even *more* important back then, we couldn't just assume
UTF-8 everywhere like we can in modern times.

Git can already do things like CRLF conversion on checking files out to
match local conventions; if you want to teach it to do character set
conversions too then I suppose that might be useful to a few developers
who've fallen through a time warp and still need it. But nobody's ever
bothered before because it just isn't necessary these days.

Please *don't* attempt to address this anachronistic and esoteric
"requirement" by dragging the kernel source back in time by three
