Well, you've just proven what Vim users have always suspected: Emacs doesn't really exist. > [1] This internal representation is based on one of the encodings > defined by the Unicode Standard, called UTF-8, for representing any > Unicode codepoint, but Emacs extends UTF-8 to represent the additional > codepoints it uses for raw 8- bit bytes and characters not unified with > Unicode. > " Do you know what those characters not unified with Unicode are? Is there a list somewhere? I've read all of the pages from here to no avail: http://www.gnu.org/software/emacs/manual/html_node/elisp/Non_002dASCII-Characters.html -- Steven -- http://mail.python.org/mailman/listinfo/python-list
