When encoding, it reassembles them into 0xC0 0xA2. In that case, it might be reasonable to ask the user whether to accept a UTF-8 file decoding that contains any raw-byte characters. What do people think of this? One problem with that is that quite often Emacs' choice of a coding system for a buffer is the result of heuristics rather than dependable information. Not making a fuzz might often be simplest. Could you explain what "fuzz" means here? -- Dr Richard Stallman President, Free Software Foundation 51 Franklin St Boston MA 02110 USA www.fsf.org www.gnu.org Skype: No way!
