 1. If a program includes non-alphanumeric-character, a problem may be occured by it.
 1. At this time, Shift_JIS is encoded or decoded as example.
 1. By the way this program(_main.py_) is a succeed case, a problem isn't basically occured.

 1. アルファベットじゃない文字を使うとそれが原因で問題が起こることがあります。
 1. 今回は、Shift_JISがエンコードもしくはデコードされた時を例にします。
 1. ちなみにこのプログラム(_main.py_)は成功例のため、問題は基本的に起こりません。
