Comment:

 Watson is right, this is an encoding issue.
 Here is a slightly better reduction of the ActiveSupport problem:

 {{{
 $ sudo macgem install activesupport
 $ macirb -rrubygems --simple-prompt
 >> require "active_support/core_ext/uri"
 Encoding::CompatibilityError: incompatible character encodings: UTF-8 and
 ASCII-8BIT
 }}}

 Here is the file in question:
 http://github.com/rails/rails/blob/master/activesupport/lib/active_support/core_ext/uri.rb

 Now the real problem can be reduced like that:

 {{{
 require 'uri'

   str = "\xE6\x97\xA5\xE6\x9C\xAC\xE8\xAA\x9E" # Ni-ho-nn-go in UTF-8,
 means Japanese.
   puts str.encoding
   parser = URI::Parser.new
   puts parser.escape(str).encoding
   str == parser.unescape(parser.escape(str))
 }}}

 The output will look like that:
 {{{
 UTF-8
 US-ASCII
 Encoding::CompatibilityError: incompatible character encodings: UTF-8 and
 ASCII-8BIT
 }}}

 The same file executed under 1.9.2 will return the following:
 {{{
 ASCII-8BIT
 US-ASCII
  => true
 }}}

 But if you add the magic encoding comment in 1.9.2:

 {{{
 UTF-8
 US-ASCII
  => true
 }}}
