Having these in a separate file from the one that's named after the module in the usual way makes it very easy to miss them when looking for tests for these two functions. (In fact when working recently on is_normalized, I'd been surprised to see no tests for it here and concluded the function had evaded being tested at all. I'd gone as far as to write up some tests myself before I spotted this other file.) Mostly this just means moving all the one file's code into the other, and moving code from the module toplevel to inside the test class to keep it tidily separate from the rest of the file's code. There's one substantive change, which reduces by a bit the amount of code to be moved: we drop the `x > sys.maxunicode` conditional and all the `RangeError` logic behind it. Now if that condition ever occurs it will cause an error at `chr(x)`, and a test failure. That's the right result because, since PEP 393 in Python 3.3, there is no longer such a thing as an "unsupported character".
