HI all,
A patch of mine from a few weeks ago made String#mb_chars use a proxy class for 1.9.x as well as 1.8. This proxy overrode some methods that were buggy in 1.9.1. but that work in 1.9.2. Since Rails officially now only supports 1.8.7 and 1.9.2, these methods should definitely no longer be overridden.
Here's the LH ticket: https://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/4978-asmultibytechars-dont-override-methods-that-work-properly-in-192#ticket-4978-2
And the commit in my fork on Github: http://github.com/norman/rails/commit/46d7d35cbaff546603fe230dda9188a9276a844b
Regards,
Norman
