注）現行の仕様ではバージョンが10を越えるQRコードが作れないことが判明しました。暇をみて改修したいと思います。
//
// QRコード生成スクリプト
// (Adobe Illustrator Windows版CS, CS2、Mac版CS,CS2,CS3にて確認済)
//
// このスクリプトは荒瀬 一彦さん(http://www.d-project.com/index.html)の
// JavaScript用QRコードのソースコードを一部改変して使用しています。
//
// 制限事項
// ・QRコードは8ビットバイト（バイナリ）モード専用です。
// ・漢字が使えません。
// ・誤り訂正レベル設定はH固定です。
//
// QRコードの検証はフリーウェア「QRコード読み取りプログラム Q太郎」
// (http://www.vector.co.jp/soft/win95/writing/se399854.html)で行いました。
