Declaration
func shouldBreakLine(byWordBeforeCharacterAt charIndex: Int) -> BoolDiscussion
The typesetter calls this method, if implemented by a subclass, before breaking a line by word-wrapping before the character at the given character index, enabling the subclass to control line breaking. A subclass can override this method to customize the text layout process. If the method returns false, the typesetter continues looking for a break point.
