Hi there

I've used your lib in my project but had two issues. HTML was not escaped (content was cut on first HTML tag as it was rendered by the browser) and the new lines were not preserved.
Here is my solution - maybe you would like to introduce this fix in the main repo:

In EmojiArea_WYSIWYG function I've changed
var html = this.$editor.text();
to
var html = this.$editor.html();
to preserve content when sharp parenthesis are used (mostly HTML).

Now, as we switch here from <textarea> to content editable <div>, new lines must be presented in HTML to be saved, hence additional line just under the previous one:
html = html.replace(/\n/g, '<br>');

Hope it helps.
Cheers
