Why Does Unicode-math And Mathastext Interact Badly?

by ADMIN 53 views

Introduction

When working with mathematical equations in LaTeX, it's essential to have a clear understanding of how different packages interact with each other. In this article, we'll explore the issue of unicode-math and mathastext interacting badly, and provide insights into how to resolve this problem.

What is unicode-math?

unicode-math is a LaTeX package that provides a way to typeset mathematics using Unicode characters. It allows for the use of OpenType math fonts, which provide a wide range of mathematical symbols and operators. This package is particularly useful for typesetting mathematics in documents that require a high level of precision and accuracy.

What is mathastext?

mathastext is a LaTeX package that allows you to use the text font for mathematical expressions. This means that mathematical symbols and operators are typeset using the same font as the rest of the text, rather than a separate math font. This package is useful for creating documents that require a consistent font style throughout.

The Problem: unicode-math and mathastext Interacting Badly

When you use both unicode-math and mathastext in the same document, you may encounter issues with the typesetting of mathematical expressions. Specifically, the two packages may interact badly, leading to incorrect typesetting of mathematical symbols and operators.

M(N)WE: A Minimal Working Example

To illustrate this issue, let's consider a minimal working example (M(N)WE) that demonstrates the problem:

\documentclass{article}
\usepackage{tikz}
\usepackage{unicode-math}
\setmainfont{Times New Roman}
\setmathfont{TeX Gyre Termes Math}
\setsansfont{Arial}
\usepackage[subdued, italic]{mathastext}
\begin{document}
This is a sample document that uses both unicode-math and mathastext.
The following equation should be typeset correctly:
${ \int_{0}^{1} x^2 \, dx }$
\end{document}

The Issue: Incorrect Typesetting of Mathematical Symbols

When you compile this document, you may notice that the mathematical symbols and operators are not typeset correctly. Specifically, the integral sign and the exponentiation operator may be typeset using the wrong font or style.

Why Does This Happen?

The issue arises because unicode-math and mathastext have different ideas about how to typeset mathematical expressions. unicode-math uses OpenType math fonts, which provide a wide range of mathematical symbols and operators, while mathastext uses the text font for mathematical expressions.

When you use both packages together, the two packages may conflict with each other, leading to incorrect typesetting of mathematical symbols and operators.

Resolving the Issue

To resolve this issue, you can try the following:

  1. Use only one package: If you only need to typeset mathematical expressions using the text font, you can use mathastext alone. If you need to use OpenType math fonts, you can use unicode-math alone. 2.Load unicode-math before mathastext**: If you need to use both packages together, try loading unicode-math before mathastext. This may help to resolve the conflict between the two packages.
  2. Use a different math font: If you're using a math font that's not compatible with unicode-math, try using a different math font that's designed to work with unicode-math.

Conclusion

In conclusion, the issue of unicode-math and mathastext interacting badly is a common problem that can arise when working with mathematical equations in LaTeX. By understanding the reasons behind this issue and trying the suggested solutions, you can resolve this problem and create documents that typeset mathematical expressions correctly.

Additional Tips and Tricks

  • Use the mathastext package with caution: While mathastext can be a useful package for creating documents with a consistent font style, it may not be the best choice for documents that require a high level of precision and accuracy.
  • Experiment with different math fonts: If you're having trouble finding a math font that works well with unicode-math, try experimenting with different math fonts to find one that meets your needs.
  • Use the unicode-math package with caution: While unicode-math is a powerful package for typesetting mathematical expressions, it may not be the best choice for documents that require a simple font style.
