Yes, this page is about library character-fold+.el,
not vanilla Emacs (e.g. library character-fold.el).
The first thing in the Commentary of character-fold+.el
;; NOTE: This library is NOT UP-TO-DATE WRT EMACS 25. The vanilla
;; Emacs library `character-fold.el', which this library
;; extends, was changed in incompatible ways after this library
;; was written. I have not yet had a chance to update this
;; (and am waiting for Emacs 25 to be released to do so).
;; Sorry about that.
(And clearly the parenthetical phrase is also not up to date.)
Dunno if/when I'll get a chance to revisit what this library did. It would be
great if vanilla Emacs offered symmetric character folding (as a choice).
