OK, you want to keep compatibility for utf8-mac but break
compatibility for utf-8-mac because you consider the original behavior
to be a bug. In that case you need to remove the alias.
 
Since emacs-22 treats utf-8-mac as utf-8, it would seem that ruby
indeed had an unrelated bug.

Backport #4489: [PATCH] Encodings with /-(unix|dos|mac)\Z/
http://redmine.ruby-lang.org/issues/4489

Author: James M. Lawrence
Status: Assigned
Priority: Normal
Assignee: Yuki Sonoda
Category: 
Target version: 


The *-dos and *-mac meta-encodings were not being recognized. utf-8-mac is a special case since it corresponds to a real encoding; its meta-encoding is utf-8-mac-mac.
