Using the following code with cocos2d-x 3 beta, you will see the notdef character is merged with the a’s and ,’s. Additionally you will notice incorrect spacing before the letter f’s and y’s.

Label *pLabel = Label::createWithTTF(“Melody town, a town of sound, where beautiful music,”, “fonts/ScriptLite.otf”, 52);
pLabel~~>setAnchorPoint;
pLabel~~>setPosition(Point(50,50));
pLabel~~>setColor);
this~~>addChild(pLabel);
