But that is _quite_ different from Emacs being _incapable_ of encoding raw bytes to a file or a stream of a specified encoding. It means that when you are using an _application_ that is expected to deliver only decodable characters, then the _application_ will _ask_ before going ahead. But the _engine_ is perfectly capable of going through here. I think that both of these are points correct. But there is still the question of what the engine should do by default. We can set the defaults for those non-frile interfaces so as to reject invalid UTF-8 sequences. Then a program could specify to override the default and allow them. -- Dr Richard Stallman President, Free Software Foundation 51 Franklin St Boston MA 02110 USA www.fsf.org www.gnu.org Skype: No way!
