# Quotation Marks Disappear After Font Change

After a font change, proper curly quotes disappear under XeLaTex (and LuaLaTex)in the area after the change, but remain properly generated in the area before the change. I can't figure out why. Both fonts have proper curly quotes in their glyph set. I've tried other secondary fonts with the same results. Here's a MWE:

%!TEX TS-program = xelatex
%!TEX encoding = UTF-8 Unicode

\documentclass[fontsize=11pt,paper=5in:8in,DIV=12]{scrbook}

\usepackage[english]{babel}

\usepackage{fontspec}
\setmainfont{Bembo Std}

• You are missing the Ligatures option: \newfontfamily\myfont{Alegreya}[Ligatures=TeX]. – Ulrike Fischer Mar 15 '17 at 16:03
• I didn't realize the word "TeX" was case sensitive. Otherwise it throws the following error: LaTeX error: "kernel/key-choice unknown" Key 'fontspec/Ligatures' accepts only a fixed set of choices. See the LaTeX3 documentation for further information. For immediate help type H return. The key 'fontspec/Ligatures' only accepts predefined values, and 'Tex' is not one of these. – user26732 Mar 15 '17 at 16:22
• Please make this an answer since the text now compiles properly. – user26732 Mar 15 '17 at 16:23
