Issue running campaigns.deploy_emergency_banner task with unicode input

[surminus]

When running the emergency publishing task, it asks that you enter some information:

Heading
Short description
More info link

If one of those inputs is a unicode character, such as including a quote ' mark, then it fails with the following error:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 10: ordinal not in range(128)

I suspect this is no longer an issue since we completely changed the way we do banner deployments.
