I'm trying to compile this code:
\documentclass{article}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@article{scottdemartinville1861,
title = {Inscription automatique des sons de l'air au moyen d'une oreille artificielle},
volume = {53},
timestamp = {2017-03-16T21:21:25Z},
langid = {french},
journaltitle = {Comptes rendus hebdomadaires des séances de l'Académie des sciences},
author = {Scott de Martinville, Édouard-Léon},
date = {1861},
pages = {108--111}
}
\end{filecontents}
\usepackage[french,english]{babel}
\usepackage{fontspec}
\usepackage[notes, natbib,doi=false,isbn=false,url=false,omitxrefdate=false,backend=biber,babel=other]{biblatex-chicago}
\bibliography{\jobname.bib}
\usepackage[autostyle]{csquotes}
\begin{document}
\autocite{scottdemartinville1861}
\printbibliography
\end{document}
The italics disappear. If I remove \usepackage{fontspec} I get the right styling. Is there any solution to this?

I'd be very surprised if this was a bug inbiblatex. – Paul Stanley Mar 21 '17 at 22:59\emphwas broken, have you updated fontspec to the7 latest release? – David Carlisle Mar 21 '17 at 23:01fontspec 2017/01/02 v2.5c. And I have added some text with\textit, and that is rendered properly. It's only the citation italics that are removed. – igm2103 Mar 21 '17 at 23:04\emphis broken. Though\textitworks properly. I don't know the difference between the two. – igm2103 Mar 21 '17 at 23:08.bibfile is self-contained): worth noting for the future. Since you are working with XeLaTeX and biber, no reason not to use proper accented characters in your.bibfile. – Paul Stanley Mar 21 '17 at 23:17
