 * @target MV MZ
 * @plugindesc Add the function to sound SE to [Display text].
 * @author Mokusei Penguin

 *
 * @help [version 1.1.1]
 * This plugin is for RPG Maker MV and MZ.
 * 
 *  [Display text] control characters:
 *   \SE[n]        # Change letter SE to n / 0 with no SE
 * 
 * ▼ Plugin command details
 *  - In MV, the variable N is referred to by writing v [N] in the item for
 *    inputting a numerical value.
 *  - In MZ, in the item to enter a numerical value, select the text and
 *    write v [N] to refer to the variable N.
 *    
 *  〇 MV / MZ
 *  
 *  〇 SetMesCharSe index
 *       index : Letter SE number
 *   - Change the letter SE to n.
 *   - The default value is 1.
 *   - The control character \SE is temporary, but in the case of a
 *     plug-in command, it is applied to all text display after execution.

 * @help [version 1.1.1]
 * このプラグインはRPGツクールMVおよびMZ用です。
 * 
 *  [文章の表示]の制御文字:
 *   \SE[n]        # 文字SEをn番に変更 / 0でSEなし
 * 
 * ▼ プラグインコマンド詳細
 *  - MVでは数値を入力する項目で v[N] と記述することで変数N番を参照します。
 *  - MZでは数値を入力する項目で、テキストを選択して v[N] と記述することで
 *    変数N番を参照します。
 *    
 *  〇 MV / MZ
 *  
 *  〇 SetMesCharSe index  / メッセージSE変更
 *       index : 文字SEの番号
 *   - 文字SEをn番に変更します。
 *   - デフォルト値は1です。
 *   - 制御文字\SEは一時的なものですが、プラグインコマンドの場合は実行後全ての
 *     文章表示に適用されます。
