String#mb_chars

== Multibyte proxy

+mb_chars+ is a multibyte 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. If the proxy class doesn't respond to a certain method, it's forwarded to the encapsulated string.

  name = 'Claus Müller'
  name.reverse # => "rell??M sualC"
  name.length  # => 13

  name.mb_chars.reverse.to_s # => "rellüM sualC"
  name.mb_chars.length       # => 12

== Method chaining

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.

  name.mb_chars.reverse.length # => 12

== Interoperability and configuration

The Chars 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.

For more information about the methods defined on the Chars proxy see ActiveSupport::Multibyte::Chars. For
information about how to change the default Multibyte behavior see ActiveSupport::Multibyte.
