Remove an old, incomplete, inappropriate attempt to preserve certain East Asian characters. tests/ChangeLog addition: 2015-05-11 Aidan Kehoe <kehoea@parhasard.net> * automated/mule-tests.el: Assert that a character which we know has no Unicode mapping is represented as REPLACEMENT CHARACTER in UTF-8, rather than as a character corresponding to a very large codepoint.
