Aircode messes up emoji font

I was experimenting with the “emoji” images in the Apple “emoji” font and I discovered (unsurprisingly) that instead of the images being visible when the code is viewed using AirCode all I see are some random characters (that are probably the unicode representation of the “emoji”), however when I edited the code once more in Codea I noticed that all the emoji had been replaced back with the random characters.

I found a work around for this - details here.
