Unicode official emojis in sender name

[Moritz Mager]

Due to the authentication problems I've copied the code to my own script account and it works! But my linked google account name contains an emoji from the unicode smileys emoticons, which causes some problems The receiver just gets a lot of question marks (e.g. ???????? for 😀). Is there any possibility to implement the feature of expressing these emojis? Thanks in advice!
