# We normalize that to always return unicode on Python2 as that's right most of the

|
# time. However, this means byte strings can round trip through yaml on Python3 but
|
|
# not on Python2. To make this code work the same on Python2 and Python3 (we want
|
|
# the Python3 behaviour) we need to change the methods in Ansible to:
|
|
# (1) Let byte strings pass through yaml without being converted on Python2
|
|
# (2) Convert byte strings to text strings before being given to pyyaml (Without this,
|
|
# strings would end up as byte strings most of the time which would mostly be wrong)
|
|
# In practice, we mostly read bytes in from files and then pass that to pyyaml, for which
|
|
# the present behavior is correct.
|
|
# This is a workaround for the current behavior.
