Updated list of failing test with py3k and a non-ascii path:
* Linux, LANG=C: test_gc test_gdb test_runpy test_zipimport
* Windows: test_email test_httpservers test_zipimport
Possible reasons:
* test_httpservers (CGIHTTPServerTestCase.setUp): test should be skipped if sys.executable is not pure ASCII (and it's not possible to create ASCII path using a symlink)
* test_zipimport: zipimport uses utf-8 (in strict mode) for the prefix, instead of the filesystem encoding
* test_gc (test_get_count): "The following two tests are fragile: ..." :-/
* test_gdb: libpython doesn't support surrogates if paths
* test_email: issue with the end of line (\n vs \r\n?)
* test_runpy: ?
