Can we use our beloved Unicode symbols like 馃挬 or are we strictly limited to ASCII?
There is great meme potential but I can understand if this was not your initial idea :P
Ehh, its not much of a question of allowance, more of support. If you think these characters are greatly supported by different OS/Browsers/Platforms e.t.c. then go for it
Actually I rethinked this question 3 minutes after so the answer is now in the QnA section on the main jam page
