Issue #4489 has been updated by Shyouhei Urabe. James sounds more natural to me. So removing UTF-8-MAC has nothing (or at least very little) to do with Emacs, right? It's about ruby's internal consistency. ---------------------------------------- Backport #4489: [PATCH] Encodings with /-(unix|dos|mac)\Z/ http://redmine.ruby-lang.org/issues/4489 Author: James M.
