ちょっとだけ詳しく
久々にvagrantを使おうと思いvagrant initしたら以下のエラーに遭遇。
$ vagrant init

そこで、以下のことを試した。
- Vagrantの再インストール
- 日本語で命名されたディレクトリやファイルがカレント以下にないかの確認
- Vagrantのコアファイルをいじる
- 端末の文字セットをShift-JISにする
空のディレクトリでコマンドを打ったので日本語名のディレクトリなどはなかった。
再インストールしたてのVagrantのコアファイルをいじるのは避けたかった。
調べを進めた結果、端末側(GitBash)の文字セットをShift-JISにすることでエラーがなくなった。
（コアファイルをいじらずに済みました。）
