# Does Kerkis font work with xelatex?

I'm a confused on whether xelatex and kerkis font can be used together. I'm using Ubuntu 13.10, Tex Live 2013/Debian, and I have the kerkis font installed. Though, if I try to compile the following snippet:

\documentclass{article}

\usepackage{fontspec}
\usepackage{xunicode}
\usepackage{xltxtra}

\usepackage{kerkis}
\setmainfont[Mapping=tex-text]{Kerkis}

\usepackage{amsmath}

\begin{document}
Hi!
\end{document}


I get the following errors:

/usr/share/texlive/texmf-dist/web2c/mktexnam: Could not map source abbreviation K for Kerkis. ... snip ... kpathsea: Running mktexmf Kerkis ! I can't find file Kerkis'. <*> ...:=ljfour; mag:=1; nonstopmode; input Kerkis ... snip ... kpathsea: Running mktexmf Kerkis ! I can't find fileKerkis'. <*> ...:=ljfour; mag:=1; nonstopmode; input Kerkis

I've searched into tex.stackexchange.com and it appears as if Kerkis works only with Babel. Is there a definitive answer? If the answer is no, what other fonts do you suggest instead ? Thanks!

• Welcome to TeX.SX! You can have a look at our starter guide to familiarize yourself further with our format. Feb 8, 2014 at 0:34
• Just a hint: When you load xltxtra you do not need anymore to load fontspec explicitely – it will be done under the hood. Feb 8, 2014 at 0:54

You need the TrueType or OpenType version of Kerkis. You can download them from the University of the Aegean site in the Kerkis page. Decompress the .zip files; install the fonts and use them:

\documentclass{article}
\usepackage{fontspec}
\setmainfont[Ligatures=TeX]{Kerkis}
\begin{document}
test
\end{document}

The Copyright belongs to the The Department of Mathematics of the University of the Aegean, Karlobasi, and the site explicitly has the follwoing warning:

If you want to use this font family in commercial work (like in books) you must include in the Copyright section the fact that you are using "Kerkis (C) Department of Mathematics, University of the Aegean".

• I'm asking myself why they aren't included in TeX Live Feb 8, 2014 at 0:31
• @egreg Perhaps a copyright issue? The Copyright belongs to the The Department of Mathematics of the University of the Aegean, Karlobasi, so this might impose some restriction to include them in TeX Live. Feb 8, 2014 at 0:34
• Thank you! It worked! The font comprehension of *tex is beyond me. Feb 8, 2014 at 0:34
• So, I wonder, why when I do 'apt-cache search kerkis' I get 'texlive-lang-greek' as a result. Plus when I do 'find /usr -name "kerkis"' I get results under /usr/share/texlive/texmf. Are they in some other format than TTF ? Feb 8, 2014 at 0:35
• @Zet yes; the font in the package is not in TT format. Feb 8, 2014 at 0:36

Although you will probably prefer to install the truetype version of the fonts as explained in Gonzalo Medina's answer, it is not true that you must do so. You can use the type 1 fonts as follows:

\documentclass{article}

\usepackage{fontspec}
\usepackage{xunicode}
\usepackage{xltxtra}
\newfontfamily\unicodefont{Latin Modern Roman}

\usepackage{kerkis}
\usepackage[T1]{fontenc}

\usepackage{amsmath}

\begin{document}
This uses legacy fonts and will not support any fontspec features which rely on opentype/truetype font specifications.

{\unicodefont For this reason, you may also wish to define a font for unicode. This is explained on page 8 of the fontspec manual.}

\end{document}


See the fontspec manual for details. While this is not the best option for Kerkis, it might be the only (or only affordable) option for other fonts in type 1 format.

• I don't think that mixing Kerkis and Latin Modern is a good idea. Feb 8, 2014 at 0:52
• @egreg Of course not. I only picked Latin Modern because I happen to know its name and I'm not sure I've got Lucida Grande which is the example in the fontspec manual. I'm certainly not recommending using this particular combination of fonts. I just have a very hazy idea of which fonts I can use with XeLaTeX since I never actually use it. 'Latin Modern Roman' is pretty much the only one I'm sure about. So I always use it as my 'sample' opentype font. Aesthetically it would obviously be a horrible choice here but which fonts I have in opentype format is, in any case, irrelevant to the OP.
