Note of the author
Isometretos is a minimal blackletter type made up of triangles on a grid
like the one commonly used for isometric projections, which is where it gets it's name,
except slightly more similar to the greek origin word "isométrētos".
It comes with upper and lower case letters, number and the more common symbols.
