void insert(BaseDocument doc, int offset) throws InvalidMarkException, BadLocationException {
BaseDocument ldoc = this.doc;
if (ldoc != null) {

}
if (offset < 0 || offset > ldoc.getLength() + 1) { // doc.getEndPosition() is valid

// treat it as an invalid document, just ignore and pass through.
// Since there should be a surrogate pair in Java and Unicode to
// represent a supplementary character.
