 *
 * @help
 * The plugin adds a line break to the text in such a way that the text does not go beyond the borders of the window.
 * The plugin works automatically for message windows and the TAA_BookMenu plugin.
 *  
 * Plugin Command: getWrappedText
 * This command will allow you to write the processed text to a variable.
 *
 * Feature of the plugin: the text color setting (\C[x]) is saved when the line is moved. Even if the new line is displayed in another window (which often happens when transferring text in the message window).
 *
 * You can always write to the author if you need support for other windows. Or if you need other features or even plugins.
