ascii codec can't encode character

[shaunmolloy]

Error:

UnicodeEncodeError: 'ascii' codec can't encode character u'\u2018' in position 51: ordinal not in range(128)

Looks like the issue happens at this line
https://github.com/jorisroovers/yamlpal/blob/master/yamlpal/yaml_parser.py#L203

Applying utf8 encoding should solve it
