The encoding-codepage gem adds a little bit of sugar for dealing with Microsoft Code Page Identifiers instead of Encoding names. Importantly, it does not add any new encodings, it just adds new names for existing encodings.

To install: gem install encoding-codepage

To use: require 'encoding-codepage'

(If you're using Bundler, you can just add gem 'encoding-codepage' to your Gemfile)

Features

Adds three methods to the Encoding class:

For looking up encodings by their Code Page Identifier:

Encoding.codepage(28591)
# => #<Encoding:CP28591>

For seeing whether encodings exist:

Encoding.exist?("CP28591")
# => #<Encoding:CP28591>

Encoding.exist?("CP37")
# => nil

For seeing whether code-pages exist:

Encoding.codepage?(28591)
# => #<Encoding:CP28591>

Encoding.codepage?(37)
# => nil

It also makes all supported Code Pages available as object with a CP prefix:

Encoding::CP28591
# => #<Encoding:CP28591>

Encoding.find("CP28591")
# => #<Encoding:CP28591>

And adds a method to Encoding objects for discovering their Code Page Identifier:

Encoding::UTF_8.codepage_id
# => 65001

Encoding::ISO_8859_1.codepage_id
# => 28591

Encodings

After installing this gem, you'll be able to access the following Code Pages from Ruby:
