To help celebrate Valentines day I've updated my UnicornHat scrolling library with a new feature: special symbols. You can now display a lovely, romantic heart (ahhhh), a silly smilie (hahah) or a scientific degrees symbol (by popular request).
To use the symbols, they are identified in the text string to be displayed by a tilde (~) prefix and a 5-character code.
For the heart: ~ heart.
The smilie: ~smile
The degrees symbol: ~degrs
For the nicely formatted results with the degrees symbol, don't leave any spaces between it and the surrounding characters. For example.
