So I want to write a document (german) with Charter and Helvetica. The problem is that I need to have lowercase upright greek letters in the body as well as in the section headers in their respective fonts.
My attempt with LaTeX:
\documentclass{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[charter,greeklowercase=upright]{mathdesign}
\usepackage{helvet}
\begin{document}
\section{Text: ä ß $\alpha$ $\beta$ $\mu$ in Helvetica}
Text: ä ß $\alpha$ $\beta$ $\mu$ in Charter
\end{document}
results in:
I guess I would need two things here:
1. a version of Helvetica with matching math support and
2. a way to input more than one math font in LaTeX.
Is this possible?
My attempt with XeLaTeX:
\documentclass{scrartcl}
\usepackage{fontspec}
\setmainfont{XCharter}
\setsansfont{Helvetica}
\begin{document}
\section{Text: ä ß α β μ in Helvetica}
Text: ä ß α β μ in Charter
\end{document}
results in:
This is almost as I want it, but XCharter does not have greek letters. So I guess I would need one of two things here:
1. a version of Charter with greek letters or
2. a way to substitute those missing glyphs in Charter from a very similar font.
I am aware of Charis SIL, but I really don't like its thickness and especially its greek letters.
Any help is much appreciated!
