// @jamestalmage FYI, for follow-redirects.

@sindresorhus Its fixed, but i'm having a small problem if compatibility.

I found 2 ways to fix this:
new Buffer(res.headers.location, 'binary').toString()
and
Buffer.from(res.headers.location, 'binary').toString()

While the first one is deprecated in v6 the second doesn't exist in v4 and since the tests check for 4, 5 and 6 i don't know how it should be.

Obs.: It's working with the first option
Obs2.: Don't merge it yet, i will write tests for this case

@sindresorhus Done. Ready to merge

Just one thing. I tried to add the following test:

http.on('/redirect-with-utf8', (req, res) => {
    res.writeHead(302, {
        location: `${http.url}/utf8-url-áé`
    });
    res.end();
});

test('redirect response contains utf8', async t => {
    t.is((await got(`${http.url}/redirect-with-utf8`)).body, 'reached');
});

But than the retry -> works on timeout errordon't pass.
Any idea what it can be?
