How do I use the inbuilt LaTeX standard fonts (in this case Times for roman, Helvetica for sans serif and Courier for mono) when using XeLaTeX and fontspec?

I have tried:

\documentclass[journal, a4paper]{IEEEtran}


     “Touché,” \textsf{he} \texttt{said}.

without success. Note that I want to be able to type utf8, non-English characters directly and therefore I use fontspec.

    The encoding of this fonts is not suitable for xelatex -- even more if you want to use characters with accents. Switch to open type fonts. Eg. \setmainfont{Times New Roman} or use the tex gyre fonts. Sep 1, 2014 at 7:43
  • The task at hand requires me to use the standard fonts specified by the class IEEEtran. Is it possible to use XeLaTeX then?

    Why would you want to use xelatex in this case? Sep 1, 2014 at 7:49

    If you are using a 'constrained' class for a specific reason, you should be cautious about adding any extra complexity. Perhaps consider sticking with pdfTeX and using \usepackage[utf8]{inputenc} or the even more 'traditional' approach of \'{e}, etc.

    the ieee seems more forgiving than most, but surely they'll use their chosen fonts when printing your paper. in this situation i would go for the simplest possible configuration of fonts. (it wasn't an issue when i was involved in publications in ieee journals...) Sep 1, 2014 at 13:42

The document @Sverre wrote, but with LuaLaTeX gives a correct output. However, as @UlrikeFischer said, it seems to be “wrong” in many ways.

%!TEX TS-program = lualatex
\usepackage{mathptmx} % Times font
\usepackage{helvet} % Helvetica font
\usepackage{courier} % Courier font
“Touché,” \textsf{he} \texttt{said}

enter image description here


If you want to be able to compile in pdfLaTeX without changing input you can

\usepackage[utf8]{\ifluatex lua\fi inputenc}

PS: I added the fontenc package that I missed before, and the document seems to work the same way as with OT1.

  • This seems to work just like I had hoped for! What is the difference between luainputenc and inputenc? The latter does not work.

  • @MunHo That it works in LuaTeX, which has a different treatment for input encodings. See my edit.

There are many way to write with your preferred fonts. Just one simple example with XeLaTeX/LuaLaTeX

% !TEX program = xelatex
% !TEX encoding = utf8



“Touché,” \textsf{he} \texttt{said}.

Another way is based on the TeX Gyre fonts

\setmainfont{TeX Gyre Termes}
\setsansfont{TeX Gyre Heros}
\setmonofont{TeX Gyre Cursor}

If you want a Math support, you can use STIX Math fonts with unicode-math package.

  • I use This is XeTeX, Version 3.14159265-2.6-0.999991 (TeX Live 2019) (preloaded format=xelatex 2019.5.8). I copied this exact file and it threw the following error: ! Package fontspec Error: The font "FreeSerif" cannot be found. What is wrong? Feb 28, 2021 at 19:39
