Which coding systems are available is platform-dependent.

Add this line to your application's Gemfile:

gem 'iconv'

And then execute:

$ bundle

Or install it yourself as:

$ gem install iconv

1. Simple conversion between two charsets.

   converted_text = Iconv.conv('iso-8859-15', 'utf-8', text)

2. Instantiate a new Iconv and use method Iconv#iconv.

    cd = Iconv.new(to, from)
    begin
      input.each { |s| output << cd.iconv(s) }
      output << cd.iconv(nil)                   # Don't forget this!
    ensure
      cd.close
    end

3. Invoke Iconv.open with a block.

    Iconv.open(to, from) do |cd|
      input.each { |s| output << cd.iconv(s) }
      output << cd.iconv(nil)
    end

4. Shorthand for (3).

    Iconv.iconv(to, from, *input.to_a)

Even if some extensions of implementation dependent are useful, DON'T USE those extensions in libraries and scripts to widely distribute. If you want to use those feature, use String#encode.

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request
