Chapter 38 LaTeX Fonts
Part of a book's style is the choice of fonts. As of 2019-11-09 we have a better understanding of the use of fonts in LaTeX to the point where we can design interfaces that will make it simpler for you to experiment with different choices and preserve various features that PreTeXt enables.
The first thing to understand is that the
xelatex engine is much more capable of employing modern fonts. TeX was built in the late 1970's when computer resources were at a premium, and the idea of mixing mathematics with non-Western languages and scripts may have been fanciful. The
pdflatex engine is rooted in this history. We now have the Unicode standard, thoroughly integrated into web browsers, and companion scalable OpenType fonts. In contrast to TeX, XeTeX was designed to work better with a multitude of fonts. So we organize this section by this distinction.
