Re: Subject: [PATCH] * lisp/progmodes/ruby-mode.el: Set `ruby-insert-encoding-magic-comment' to nil by default.

[Bozhidar Batsov]

I cannot imagine why would anyone want to use any encoding other than utf-8 for their code. As for Ruby 1.9 - I think it makes sense to simply set the magic comment to utf-8 if a file contains non-ascii characters. Keep in mind that I'm not suggesting to remove the functionality, but simply to disable it by default, since it's not something that most Ruby hackers today would want to use.

IIUC, Ruby-2.0 doesn't require source code to be utf-8, so the
magic-comment is not obsolete.  IOW, what needs to be done is to make
Emacs prefer utf-8 for ruby files (it's probably the case already), and
to make ruby-mode-set-encoding only insert the magic comment if it is
different from utf-8.
