Hi,
When using PyInquirer with python2 I face a problem when the options include non-ascii characters.
Python3 works fine though.
Here is a minimal working example that demonstrates this behaviour.
# -*- coding: utf-8 -*-
from __future__ import print_function, unicode_literals
from PyInquirer import prompt
def main():
choice = 'John’s Pizza'
questions = [
{
'type': 'list',
'name': 'pizza',
'message': 'Pizzeria:',
'choices' : [choice]
}
]
answer = prompt(questions)
pizza = answer['pizza']
print('Answer is |' + pizza + '|' )
if __name__ == '__main__':
main()
Python3 execution:
❯ python3 encoding-test.py ? Pizzeria: John’s Pizza Answer is |John’s Pizza|
Python2 execution:
❯ python2 encoding-test.py
? Pizzeria: (Use arrow keys)
Traceback (most recent call last):

UnicodeEncodeError: 'ascii' codec can't encode character u'\u2019' in position 4: ordinal not in range(128)
The apostrophe unicode character is what is breaking the python2 execution.
