xelatex

问题 I'm trying to use Calibri font, but from what I understand I first need to be able to use the xelatex engine. This is where I run into problems. Sample code and error are below. Please note that I am very new to latex so chances are I missed something obvious. If it matters I have MikTeX 2.9 installed, and I have successfully generated pdfs using the default pdflatex engine (from what I understand this has very limited fonts.) I'm on windows 10 64 bit. --- header-includes: - \usepackage
