After the first time I asked this question, I only got down votes. So I thought, probably there isn’t any other plugin out there and I developed my own based on Emojiarea (which also Webogram uses). Because I didn’t copy the code from Webogram, I didn’t sort the icons yet but my solution works how I excepted it.
The custom plugin can be found on my Github Account https://github.com/GittiHab/jquery-emojiarea.
I hope this helps others with a similar problem and takes away some work.
