Can you add a test to ensure got and responseType: 'buffer' works even when the encoding option is set?

[sindresorhus]

You need to remove the null and Buffer mention here: https://github.com/sindresorhus/got#encoding And also say that it only applies when the response type is some kind of string.

[sindresorhus]

You also need to update:

test/progress.ts
74:	const {body} = await got({encoding: null})
95:	const stream = got.stream({encoding: null})

[sindresorhus]

I think we should throw if got({encoding: null}) saying that the user should use got({responseType: 'buffer'}) instead.
