[issue35014] asyncio subprocess accepts string as parameter which lead to UnicodeEncodeError

[Rémy Hubscher [:natim]]

I believe Python 3.7 brings explicit unicode encoding/decoding.

If depending on the environment the create_subprocess_exec method can fail, I believe we should not try to encode the command lines attribute but rather enforce it to be bytes.
