Re: 23.0.50; utf7-decode failed with non latin-1 charactor

[Richard Stallman]

    There appear to be two different implementations of utf-7 in Emacs, one
    in lisp/international/utf-7.el, and one in lisp/gnus/utf7.el

    The former seems to work for decoding, but always returns nil on
    encoding without changing the buffer contents (the correctly encoded
    text is in a buffer called " *temp*" however).

    The latter only seems to work on Latin-1 text (as documented in the
    commentary) and returns results from the encoder that are inconsistent
    with iconv.

    Probably lisp/international/utf-7.el should be fixed, and the Gnus one
    dropped.

Handa, can you fix international/utf-7.el?
