Has anybody created an emoji keyboard that’s actually a piano keyboard for writing musical notation? Wanted a quick way to tweet a melody.

Inspired by @AudioGrains tweet, I made this little Emoji Piano.
Emoji Piano lets you create simple melodies and encodes them with Unicode emojis which you can share and tweet.
Currently, it uses system fonts. This means it does not depend on the app but on your browser and your system, how the emojis are displayed.
This is why you could see tofu with some setups (tofu are small boxes that are displayed when no font that supports this character is available to the computer).
The following pictures show some screenshots taken from different browsers running on different machines:
As you can see, Windows 7 does not provide fonts with all Unicode emojis. Besides, it does not support color fonts at all. You need at least Windows 8.1 for color fonts.
