Zappa init: UnicodeDecodeError

On Zappa init, possible issue with encoding using CP1252 with a flask application?

Context

On Zappa init, when defining the S3 bucket, Zappa errors out with a decode error:

AWS Lambda and API Gateway are only available in certain regions. Let's check to make sure you have a profile set up in one that will work.
Okay, using profile default!

Your Zappa deployments will need to be uploaded to a private S3 bucket.
If you don't have a bucket yet, we'll create one for you too.
What do you want call your bucket? (default 'zappa-5u4ed22rq'):

It looks like this is a Flask application.
Oh no! An error occurred! :(

UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 301: character maps to <undefined>

Expected Behavior

Zappa init should run through the process and produce a dictionary of values / config.

Actual Behavior

A decode error generated

Possible Fix

Are adding coding statements to the top of an api.py file necessary?

Steps to Reproduce

Install the newest version of Anaconda
install virtualenv
install zappa, flask, awscli
create an S3 bucket
write api.py code
run zappa init

I got the same error too. I am using the virtual environment on windows10, python3.6 and Zappa0.46.1 Also, in utilities.py, it was updated to io.open(full, 'r', encoding='utf-8') as f but I got same error.

Any help would be highly appreciated
