Support for unicode

[alecjacobson]

The following works as expected:

# README

$\phi^2 \ge 0, \forall \in R$

Mathjax and other tex compilers will allow unicode input (probably by including \usepackage[utf8x]{inputenc}). If I use readme2tex directly this will not work

# README 

$φ² ≥  0, ∀ φ ∈ R$

and instead quietly outputs 0,R for the math part.

Is it possible to achieve this? If not, I'd like to request unicode support as a feature.
