In the following code when I am using \usepackage[greek,english]{babel} everything works fine until I try to use \selectlanguage{greek} then I get that error and those warnings:

! Corrupted NFSS tables.wrong@fontshape ...message {Corrupted NFSS tables}error@fontshape else let f... \selectlanguage{greek}

Font shape LGR/GFSArtemisia(0)/m/n' undefined(Font) usingLGR/cmr/m/n' instead

Font shape LGR/GFSArtemisia(0)/m/n' undefined(Font) usingEU1/lmr/m/n' instead

Some font shapes were not available, defaults substituted.

On the other hand when I am trying to use \usepackage[engish,greek]{babel} I will not even bother to mention how many problems I get!

I use XeLaTeX and Texmaker.

What is going on? How can I fix this?

This is the worst case using \usepackage[engish,greek]{babel}.

\documentclass[12pt]{article}

\usepackage[top=0.7in, bottom=1.2in, left=0.8in, right=0.8in]{geometry}

\setlength{\parindent}{0cm}

\usepackage[english,greek]{babel}

\usepackage{fontspec}

\setmainfont[
  Ligatures=TeX,
  Extension=.otf,
  UprightFont=*,
  BoldFont=*Bold,
  ItalicFont=*It,
  BoldItalicFont=*BoldIt,
  Mapping=tex-text,
]{GFSArtemisia}

\setsansfont[Mapping=tex-text]{GFSArtemisia.otf}

\usepackage[fleqn]{amsmath}

\usepackage{unicode-math}

\newcommand{\en}[1]{\foreignlanguage{english}{#1}}

\begin{document}

$\overline{x}=\left[
\begin{array}{c}

\text{Feature2}\\
\text{Feature2}\\
\end{array}
\right]$

\end{document}
  • Load fontspec before babel. But I don't see any \selectlanguage{greek} in your example. Please, help us to help you: MWE should reproduce the error you get. This one doesn't. – egreg Oct 12 '14 at 22:49

  • fontspec works better with poliglossia – skpblack Oct 12 '14 at 23:27

The error is in loading babel before fontspec, which sets the document encoding to EU1 (with XeLaTeX) or EU2 (with LuaLaTeX). When this fact is known, babel is able to load the Greek language adapting it for those engines, without doing the tricks it has to do with the LGR encoding for pdflatex.

This might be improved in babel, but the remedy is very simple:

load fontspec before babel

Here's a polished up version:

\documentclass[12pt]{article}

\usepackage[fleqn]{amsmath}
\usepackage{unicode-math}
\usepackage[english,greek]{babel}

\setmainfont[
  Ligatures=TeX,
  Extension=.otf,
  UprightFont=*,
  BoldFont=*Bold,
  ItalicFont=*It,
  BoldItalicFont=*BoldIt,
  Mapping=tex-text,
]{GFSArtemisia}

\begin{document}

Ένα πρότυπο (ή αντικείμενο) καθορίζεται από ένα διάνυσμα μετρήσεων που ονομάζονται
χαρακτηριστικά. Το διάνυσμα ονομάζεται διάνυσμα χαρακτηριστικών.

$\overline{x}=\left[
\begin{array}{c}
\text{Feature1}\\
\text{Feature2}\\
\text{Feature2}\\
\end{array}
\right]$

\end{document}

Note that unicode-math also loads fontspec; however, using Latin Modern Math with Artemisia is not really the best, in my opinion.

Also declaring Artemisia as the sans serif font is questionable.

  • Thank you for your answer but I tried loading fontspec before babel when I saw your comment and I had countless errors. Even your version when I compile it produces errors and warnings. I use Texmaker if this makes any different and xelatex. I will add it to my question in case it helps. – Adam Oct 12 '14 at 23:16
  • @Adam Texmaker doesn't make any difference. The TeX distribution may, if it's not up-to-date. – egreg Oct 12 '14 at 23:28
  • I downloaded it last year so I think is up-to-date. – Adam Oct 12 '14 at 23:30
  • If it's TeX Live 2013, it isn't. – egreg Oct 12 '14 at 23:30

    Also MiKTeX needs updates. Please, ensure you have all the packages to their last release. – egreg Oct 12 '14 at 23:40
