 * OK, this method looks complicated now(2009/05/05).  Because input escText may include some uniqueKey, which is replacement of HTML tag.
 * These uniqueKey won't be calculated into leadNonWord or endNonWord,i.e., not as border. For example, 
 * 
 * my text uniqueK[text]uniqueK has key. (Originally, this text looks like "my text <p>[text]</p> has key.", P tag is replace into uniqueK)
