Rails Ruby on Rails

Significantly improved internal encoding heuristics and support.

• Default Encoding.default_internal to UTF-8
• Eliminated the use of file-wide magic comments to coerce code evaluated inside the file
• Read templates as BINARY, use default_external or template-wide magic comments inside the Template to set the initial encoding
  • This means that template handlers in Ruby 1.9 will receive Strings encoded in default_internal (UTF-8 by default)
• Create a better Exception for encoding issues, and use it when the template source has bytes that are not compatible with the specified encoding
• Allow template handlers to opt-into handling BINARY. If they do so, they need to do some of their own manual encoding work
• Added a "Configuration Gotchas" section to the intro Rails Guide instructing users to use UTF-8 for everything
• Use config.encoding= in Ruby 1.8, and raise if a value that is an invalid $KCODE value is used

Also:
* Fixed a few tests that were assert() rather than assert_equal() and were caught by Minitest requiring a String for the message * Fixed a test where an assert_select was misformed, also caught by Minitest being more restrictive * Fixed a test where a Rack response was returning a String rather than an Enumerable http://github.com/rails/rails/commit/64d109e3539ad600f58536d3ecabd2...
