Upgraded to Rails 2.0.2, except that we maintain vendor/rails/actionpack/lib/action_controller/routing.rb from Rail 1.2.6 (at least for now), so that Routes don't change. We still get to enjoy Rails's many new features. Also fixed a bug in Chunk-handling: disable WikiWord processing in tags (for real this time).

# +chars+ is a Unicode safe proxy for string methods. It creates and returns an instance of the
|
|
# ActiveSupport::Multibyte::Chars class which encapsulates the original string. A Unicode safe version of all
|
|
# the String methods are defined on this proxy class. Undefined methods are forwarded to String, so all of the
|
|
# string overrides can also be called through the +chars+ proxy.

# All the methods on the chars proxy which normally return a string will return a Chars object. This allows
|
|
# method chaining on the result of any of these methods.

# The Char object tries to be as interchangeable with String objects as possible: sorting and comparing between
|
|
# String and Char work like expected. The bang! methods change the internal string representation in the Chars
|
|
# object. Interoperability problems can be resolved easily with a +to_s+ call.
