I would like to use my custom font for mathematical symbols like integrals and summation. I have a font file (Font.ttf) with my own font, the same gets applied to numbers, letters and operators (+-) but not to integrals or summation or the operator (▽).
The following is the code.
\documentclass[a4paper, 20pt]{extarticle}
\usepackage{mathspec}
\setmainfont{Font.ttf}
\usepackage{mathastext}
\setmathrm{Font}
\setmathfont(Greek)[Uppercase=Regular,Lowercase=Regular]{Font}
\begin{document}
\begin{equation}
\int_{a}^{b}5a^2_5-a^2 dx = \frac{\sin \theta}{x}
\end{equation}
$$ \lambda \alpha \beta \nabla sin sin ( \delta) \Delta \theta$$
\end{document}
The output:
Quick Note: I m a beginner to the language, hence try answering in a beginner friendly manner.
Edit 1 I would like it add that I recently came across MnSymbol package which I feel could be useful in this scenario. However, m unable to find how to use the same.
