    Charwidth.normalize!("Ｈｅｌｌｏ，　Ｗｏｒｌｄ！") # destructive
    Charwidth.normalize("｢ﾊﾛｰﾜｰﾙﾄﾞ｣") # => "「ハローワールド」"

Or extend String class.

    require "charwidth/string"
    "Ｈｅｌｌｏ，　Ｗｏｒｌｄ！".normalize_charwidth # => "Hello, World!"
    "Ｈｅｌｌｏ，　Ｗｏｒｌｄ！".normalize_charwidth! # => destructive
    "｢ﾊﾛｰﾜｰﾙﾄﾞ｣".normalize_charwidth # => "「ハローワールド」"

# ActiveRecord integration

    require "charwidth/active_record"

    class Article < ActiveRecord::Base
    end

    a = Article.new(title: "Ｈｅｌｌｏ，　Ｗｏｒｌｄ！")
    a.title # => "Hello, World!"

# CLI

    # Call charwidth command with arguments
    $ charwidth "Ｈｅｌｌｏ，　Ｗｏｒｌｄ！"
