It doesn't appear in the Emacs Lisp ref manual, so I suppose it is a concept from Scheme. How would it relate into Emacs? Maybe your suggestion is a good one. It doesn't matter how these raw bytes are encoded internally. No matter what mechanism we use to accomplish it, propagating invalid byte sequences by default is bad security policy. As a general matter, the policy that programs should not get upset when they see invalid UTF-8 seems more secure than the policy that programs should not propagate invalid UTF-8. But, given the situation, it isn't useful to debate that theoretical question. -- Dr Richard Stallman President, Free Software Foundation 51 Franklin St Boston MA 02110 USA www.fsf.org www.gnu.org Skype: No way!
