Check for encodings in get_file tests and fix some bad implementations.
Review Request #9790 — Created March 15, 2018 and submitted — Latest diff uploaded
We had a couple hosting services (Beanstalk and Kiln) that were
returning Unicode strings instead of byte strings in theirget_file()
implementations. This fixes those and adds checks to all test suites
currently testingget_file().
Unit tests pass.
