      That seems to be the same bug, Marc reported:
      ,----
      | Multi-byte problem? Marc Weber
      | echo matchlist('1', '\%#=1\o{\?Ä\Z')
      | echo matchlist('1', '\%#=2\o{\?Ä\Z')
      `----

      which simpler written:
      echo matchlist('1', '\%#=1Ä\Z')
      echo matchlist('1', '\%#=2Ä\Z')

      (sorry, no patch yet)

      regards,
      Christian
