Empty tweets when Emojis are used as first character

[pixelbrackets]

If an Emoji is used in a tweet and it is is the leading character, then the whole field will be empty. Tweetnest will then show an empty tweet.

If Emojis are placed somewhere else, they are removed and the text is cropped from this point on.

Emojis are UTF8MB4 characters. A MySQL database with a charset like »utf8_unicode_ci« is not able to store these characters correctly. Solution:

• Change the field to »utf8mb4_unicode_ci« in your installation (see https://mathiasbynens.be/notes/mysql-utf8mb4)
• …if this is not possible (e.g. because your hoster does not support a MySQL version with UTF8MB4), then convert the text field from »varchar« to »blob«. Change it back to varchar, as soon as UTF8MB4 is available. (see http://stackoverflow.com/questions/18726423/how-to-insert-emoji-utf8-4-byte-characters-into-mysql-5-5)
