Which part of what I wrote led you to that conclusion? That's not what I meant, not at all. What I meant was that a Lisp program is broken if it uses 'length' to compute how many glyphs (the accurate term is "grapheme clusters", not "glyphs") correspond to the characters of a string. It should use 'string-width' instead.
