Support for new languages and emojis.

I noticed a lot of fonts such as chinese and emojis were not supported. A workaround for users is to update the character set through phpmyadmin or on sql shell with below commamd:

ALTER TABLE tablename CONVERT TO CHARACTER SET utf8mb4, COLLATE utf8mb4_bin;

I would recommend the developer to update to this character set.
