Figure out how to handle special characters

[gavinhenderson]

Currently there is no way to for a user to enter special characters (unless they come up in prediction).

We could just put them at the end of the list, but then they would be far away. Its a tough balance because special characters would make the list really long, but it would allow users to enter 'correct' grammer. However, voice engines dont need correct grammer, so do we just force incorrect grammer for simplicity?

For ref, pasco didn't allow special characters
