Keys and values in request.args are returned as byes in Python3

With Python3, the keys and values for request.args returned when submitting form data to an app.route are returned as bytes, not strings.

2020-06-29 23:11:10-0400 [-] (Pdb) {b'username': [b'irowell'], b'email': [b'test@gmail.com'], b'password': [b'test']}
request.args['username']
2020-06-29 23:11:21-0400 [-] (Pdb) *** KeyError: 'username'
request.args[b'username']
2020-06-29 23:20:01-0400 [-] (Pdb) [b'irowell']

So either the user would have to convert the kv pairs to string before parsing, or use bytes when looking up values in the dictionary. Is there anythign that handles this natively?

Start by reproducing the Python 3 behavior described for request.args when form data is submitted to an app.route, then trace where its keys and values are parsed. Done means string keys such as 'username' work for lookup without caller-side conversion, with a regression test covering the reported request.
