Here’s a list of all of them. I think there are 498 symbols. They are HTML entities. The forum will print them differently than in the game. If enough people are interested in the game, I could try to improve it a bit. That one hasn’t been updated in a long time.
The game is here, for anyone who hasn’t tried it:
