Because the AMS, MathSci TEX, STIX, and math fonts in general have consistently
made distinctions between such entities as phi and straightphi,
epsilon and straightepsilon, etc. And mathematicians may make the
distinctions. Compared to the complexity involved in contracting
a compact analytic subspace X of codimension one in the r-dimensional
complex analytic space U to a normal isolated singularity, I
think we can consider distinguishing a variable named epsilon
from some other entity named straightepsilon to be rather tame,
don't you think?

We know that, and final sigma is not in the sets to be encoded.
Nor are digamma, koppa, sampi, &c.
