Overview

A helper to use instead the builtin IO class to read files in correct encoding.

By default in Ruby 1.9 the encoding is auto-detected, which can have surprising results. So in here we read in all files in UTF-8 (the default) or in some other encoding specified through –encoding option and convert it to UTF-8 internally.

@@encoding =
