And I'm not quite sure that such a function really makes sense. How often do you reverse a string for display purposes, anyway? But it might make sense to add function to tokenize a string into grapheme clusters -- I can see that being useful. Then the caller can chop and reverse the list of clusters as they wish. `string-tokenize-graphemes'? -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
