Greek Alphabet

[YakoYakoYokuYoku]

This issue is a feature request for the Greek Alphabet to be included. I'm an user of this font and I'm marveled with the excellent work done here. Although one time I wanted to use Greek text with it, but I've noticed that only a few characters, like Delta and Omega, are there solely for mathematical usage. If it's possible to have the rest of the alphabet I'd be glad for.
