Notification language

Please can you try connecting with the Web IDE and pasting in:

require("messages").pushMessage({"t":"ad­d","id":1575479849,"src":"Skype","title"­:"\uc548\ub155\ud558\uc138\uc694\u0020\u­c138\uc0c1","body":"\uc548\ub155\ud558\u­c138\uc694\u0020\uc138\uc0c1",positive:1­,negative:1})

and see what happens? And you definitely installed the all languages font and not the 150 languages one?
