The issue that prompted me to revive this is actually related to hash access. Here's what I was doing:

    @clients.group_by {|p| p.name.mb_chars.first }

This gives me back an array that is the same size as the original @clients array because it sees each Chars string as different.

I understand your desire for it to be symmetric with String#eql?, but I think that is a separate issue. I don't feel strongly about it one way or the other. At a minimum, #eql? and #hash should behave properly when compared to another Chars object.

Hi Brandon,

The reason I dropped Chars#eql? is because I wanted String#eql? and
Chars#eql? to be symmetric. This can't be done without redefining
String#eql? and I felt at the time that redefining core lib methods
might be a bit much.

I guess if the core team doesn't mind changing String#eql? I wouldn't
mind either. But the patch doesn't really make and sense without it.

I definately don't feel alright with implementing Chars#hash, because
of the internal optimizations of Hash in Ruby you can never get this
to work consistently. It's better to not support it at all than doing
a half-assed job.

If you want to implement eql?, please open a new ticket because the
ticket you're referring to was more about hash access than eql?.

I just upgraded an application to 2.3 RC2 and had several failing
features stemming from ActiveSupport::Multibyte::Chars #eql? behaving
differently in Ruby 1.8.x from 1.9.

There was an old ticket with a patch and then some suggestions for
fixing it that had be come stale, so I created a new patch
incorporating the suggestion.

I'd appreciate it if someone could check it out and apply it for 2.3.
