I propose: radio links should be delimited by characters that don't match [:alpha:] in emacs' regular expression syntax. Letters (like: aá書ĉ) match, and delimiters (like: -'"/) don't. Test it with: : (string-match-p "[[:alpha:]]" "á") : (string-match-p "[[:alpha:]]" "書") : (string-match-p "[[:alpha:]]" "ĉ") : (string-match-p "[[:alpha:]]" "'") : (string-match-p "[[:alpha:]]" "-") And the opposite: check for non-letterness: : (string-match-p "[^[:alpha:]]" "-") : (string-match-p "[^[:alpha:]]" "á") So a radio link with LINK_TEXT should not only be a match of the regexp "LINK_TEXT" but of "[^[:alpha:]]LINK_TEXT[^[:alpha:]]" (well, make it something like "(^|non-letter)LINK_TEXT($|non-text)". I think that's better than the current solution and stills allows for radio links which contain non-letters, like <<<o'clock>>>. What do you think? Daniel
