Missing Greek characters

[BPMinaker]

Is your feature request related to a problem? Please describe.
I use Recursive when writing Julia programs in VS Code. Julia lets me write equations that include Greek characters in my code. Recursive is missing omega, zeta, rho, tau, sigma, and a few more characters that appear frequently in many science and engineering expressions.

Describe the solution you'd like
Please expand the Greek character support. JuliaMono and Cascadia Code both have larger Greek character sets, but I much prefer Recursive.
