WP-UnFormating is a simple plugin. As a result, the content enclosed with special tag releases the format.
I gathered some functions and some variables in class.
I was optional and was able to set a parameter.The option supports template tags.
I revised it so that '$n' was not converted.
I was able to apply this plugin in "the_content" first.
Bug Fix. When there was square brackets in options, malfunction occurred.
