Comment(by batterseapower):
You are seeing exactly the expected output. My recent change to have
mkTextEncoding try our Haskell TextEncodings before it falls back to iconv
may have made this better.
In practice, we don't really care whether UTF-16//ROUNDTRIP works because
we only use //ROUNDTRIP for the fileSystemEncoding (a modified
localeEncoding), UTF-16 is not an ASCII superset, and IIRC the Posix
standard requires the locale encoding to be an ASCII superset.
