One more argument - How many people use a proportional font to view Emacs-Lisp code? With a fixed font, the code is _less_ legible using the em-dash character than the escape sequence. Why? Because the difference between a normal hyphen character and an em-dash character in most fixed-width fonts is imperceptible.
IOW, when the code is not broken because of Web access or browser problems, it looks pretty much like this: (let ((underline (if (char-displayable-p ?-) ?- ?-))) ... So much for legibility of the code, bis. Hence the big honkin comment: ;; Use U+2014 (EM DASH) to underline if possible, else U+002D (HYPHEN-MINUS) So much for avoiding the nastiness of ?\u2014. U+2014 is much better... _______________________________________________ emacs-pretest-bug mailing list [email protected] http://lists.gnu.org/mailman/listinfo/emacs-pretest-bug
