String, Get Number of Characters

// Nashorn Script (engine type: 1)
// 
// Notes:
// Counts consecutive spaces (including tabs and double-byte spaces) as one character.
// Use C if you do not want to count linefeed codes as characters.
// Use D if you do not want to count linefeed codes and spaces as characters.
// 
// Notes (ja):
// 連続する空白（タブや全角空白も含む）は全体で１文字とカウントされます。
// 改行コードを文字数にカウントしたくない場合はCを使用してください。
// 改行コードと空白を文字数にカウントしたくない場合はDを使用してください。
