Describe the bug

• Node.js version: v14.18.3
• OS & version: OSX 12.1

The encoding option is not working when combined with responseType: 'json'.

Actual behavior

I created a minimal repro repo : https://github.com/baptistemarchand/got-encoding-repro/blob/main/index.mjs

  const res1 = await got('https://latin1-api.vercel.app/', {
    encoding: 'latin1',
    responseType: 'json',
  })
  // Outputs: {data: "?"} 
  console.log('res1', res1.body)

  const res2 = await got('https://latin1-api.vercel.app/', {
    encoding: 'latin1',
  })
  // Outputs: {data: "é"} 
  console.log('res2', JSON.parse(res2.body))

What it does :
I have a dummy api that returns a JSON with the latin1 encoding : https://latin1-api.vercel.app/.
I call it twice with got :

• once with responseType: 'json' => the encoding seems to be ignored
• once without responseType: 'json' and instead doing a JSON.parse manually => encoding working as expected
  Here is the result :
  

Expected behavior

I expected the result of both console.log to be the same. Like this :

res1 { data: 'é' }
res2 { data: 'é' }

Checklist

• I have read the documentation.
• I have tried my code with the latest version of Node.js and Got.
