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 says this: ;; 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= ).
