Using Chalkduster font in XeLaTeX correctly

Question

I'm trying to use the Chalkduster font by adding in my preamble:

\usepackage[no-math]{fontspec}
\setmainfont[Mapping=tex-text]{Chalkduster}
\usepackage[defaultmathsizes]{mathastext}

After that, when I compile with XeLaTeX it works OK, except for greek letters. For example below, only the font of \mu doesn't change.

\documentclass[10pt]{article}
\usepackage{amsmath} %maths
\usepackage[utf8]{inputenc} %
\usepackage[no-math]{fontspec}
\setmainfont[Mapping=tex-text]{Chalkduster}
\usepackage[defaultmathsizes]{mathastext}
\begin{document}
This is my test:
$$g(y) = \dfrac{w(y) f(y)}{\mu}$$
\end{document}

Is there a way to fix this? Thanks in advance.

Answer 1

Looks like Chalkduster is intended as a handwritten-style ornamental font for Latin letters, from a long time ago. Its mathematical support is barely minimal, if that.

Confirming @Marijn, Chalkduster has a glyph called "Delta" sitting in the Laplace Operator slot (U+2206 INCREMENT : Laplace operator, forward difference, symmetric difference (in set theory))

and Omega and Pi in the Greek and Coptic unicode block:
