This `u` is different than the one in compatibility. That u is for doing unicode escape characters, e.g. `u('\u2020')`, and so calls `codecs.unicode_escape_decode`. Because the print test files are utf-8, they need to decode the characters rather than escape them. This is only done when doing printing tests, so I didn't put it in the compatibility file. But, I can import this one from the main pretty print tests.
