Python － メールの日本語対応化・・・（嬉）

先ほど失敗してエポケーしたはずだったが、しつこくpythonのメール関連のページを
見ていたら参考していたサイトに答えは載っていた・・・ｗ
ウノウラボ by Zynga Japan: Pythonでメールを送信したい人のためのサンプル集

一番下のコメントにある、

msg = MIMEText(body, 'plain', encoding)
↓
msg = MIMEText(body.encode(encoding), 'plain', encoding)
これで文字化けせずにメールが受信できた～（嬉）

とかいいながらウキウキと「馬鹿野郎～」とかつけて送信したらまたエラーｗ
なんだよ・・・と思って成功した時は「あいうえお、かきくけこ」だったので
「あいうえお、かきくけこ～」でテストしたら再現できた。「～」が犯人か。
いろいろ、調べると・・・むむ・・・エンコードの'ISO-2022-JP'ってシビアなのね。
PythonJISX0213 – アクセンスのおまけ

もう！・・・別に読めればいいんだから'ISO-2022-JP'の必要ないんじゃ・・・？
こりゃ、エンコードは'utf-8'でいいよね？

テストしたら「㌧㌦㍑～」も含めてエラーもなし。
＃コードはuploadとかできないのか・・・
