Support UTF-8 emojis

[m4dz]

Actually, events in calendar views doesn't rely very well on UTF-8 emojis chars (see attached screenshot, event summary input was "WE :heart:". It synchronized correctly but isn't properly rendered.

Note: rendering emojis is certainly due to font rendering, not especially related to calendar app. So the problem can occurs everywhere on the plqteform but should be fixed widely :wink:.

I've read on several SO posts that only some fonts are able to render the emojis (DejaVu Sans, for instance) Besides, there's a project on github named php-emoji, which may help (didn't dive into it at all): https://github.com/iamcal/php-emoji

And then of course, I realize there's no PHP :) Use to play with PHP too much ^_^

But, hey, in case the repo helps for another project ... :D
