有没有String.force_encoding()在Ruby 1.8.7(或Rails 2.x)中使用的解决方案,以便它像在Ruby 1.9中一样工作？我读了一些关于require的内容active_support,但这不起作用

$> gem list --local | grep'rails\| activesupport'

 activesupport (3.0.3, 2.3.8, 2.3.5)
 rails (2.3.8, 2.3.5)

$> ruby -v

ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-darwin10.4.0]

$> rails -v

Rails 2.3.8

IRB:

> require "rubygems"
=> true 
> require "active_support"
=> true 
> "asdf".force_encoding("UTF-8")
NoMethodError: undefined method `force_encoding' for "asdf":String
> String.respond_to?(:force_encoding)
=> false
