But, we allow decode-coding-region in a multibyte buffer. Then, it's strange not to allow something like this: (decode-coding-string (buffer-substring FROM TO) CODING) >> It's not a trivial work to change the current code (in coding.c) to signal >> an error safely while doing a code conversion. > If by "safely" you mean "which will not break currently working code", > I agree. If by "safely" you mean "which will not break properly written > code", I disagree. I mean by "safely" to signal an error only at a safe place, i.e., the place where we can do a global exit. For instance, we can't signal an error in decode_coding_iso2022 because it may be modifying buffer contents directly. By the way, what do you mean by "properly written code"? --- Ken'ichi HANDA [EMAIL PROTECTED] _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-devel
