Exactly.  Their use in natural-language text
isn't problematic, in general.  Their use in
contexts where their meanings are important
is problematic.  For example use in regexps:

(defvar info-quotation-regexp
  (concat
   "\"\\(?:[^\"\\]\\|\\\\\\(?:.\\|\n\\)\\)*\"\\|" ; "..."
   "`\\(?:[^']\\|\\\\\\(?:.\\|\n\\)\\)+'\\|"      ; `...'
   "‘\\(?:[^’]\\|\\\\\\(?:.\\|\n\\)\\)+’\\|"      ; ‘...’
   "“\\(?:[^”]\\|\\\\\\(?:.\\|\n\\)\\)+”"         ; “...”
   )
  "Regexp to match `...', ‘...’, “...”, \"...\".
If ... contains an end char then that char must be backslashed.")
