  This fixes a missing .lower() on the encoding name, a wrong byte undecodable by UTF-8, a wrong variable name, hopefully some windows buildbot on 3.x and adds a proper skip. It might break other things though.

  r78689 enabled the test on more platforms but the buildbot did not like it. Using the filesystem encoding might work better. Also see #5604.

  sys.getdefaultencoding() can return None.

  Cleanup and minor fixes.

  The test was failing because the curdir was missing from sys.path. This should fix the problem.
