Fonts & Character Sets ⇒ Dioxipe+Polyglossia=Blank PDF

[AleCes]

Hello everybody,
The Dioxipe font seems to be at odds with polyglossia when used to typeset Greek characters.

Code: Select all

\documentclass{book}
\usepackage{fontspec}
\defaultfontfeatures{Mapping=tex-text}
\setmainfont{Dioxipe}
%\newfontfamily\greekfont{Dioxipe} if I fail to add this, I get an error
\usepackage{polyglossia}
\setmainlanguage[variant=ancient]{greek}
\setotherlanguages{english}
\usepackage{xunicode}
\usepackage{xltxtra}

\begin{document}

ᾶῆῶῦῖ \textenglish{abcd}

\end{document}

The output I get is a blank pdf.

I don't have the font and din't find some dowload link, and a quick google search lead me to UNICODE GREEK FONTS.

Maybe there is another Font suitable for your needs.

Now, let me take a look at the problem at hand.

Code: Select all

\documentclass{book}
\usepackage{fontspec}
\defaultfontfeatures{Mapping=tex-text}
%\setmainfont{Dioxipe}
\setmainfont{ufonts.com_dioxipe-opentype.otf}
\newfontfamily\greekfont{ufonts.com_dioxipe-opentype.otf}
\usepackage{polyglossia}
\setmainlanguage[variant=ancient]{greek}
\setotherlanguages{english}
\usepackage{xunicode}


\begin{document}

\pagestyle{empty}
ᾶῆῶῦῖ\par
\textenglish{abcd}\par
\fontspec{Latin Modern Roman}abcd

\end{document}

The code above gives me the expected output. Polyglossia requires you to set a greek font and issues errors instead. The page isn't empty, though.

Let's proove it by stripping down the document even more:

Code: Select all

\documentclass{book}
\usepackage{fontspec}
\defaultfontfeatures{Mapping=tex-text}
\setmainfont{ufonts.com_dioxipe-opentype.otf}
\begin{document}
\pagestyle{empty}
ᾶῆῶῦῖ\par
{\fontspec{Latin Modern Roman}abcd\par}
abcd
\end{document}

Thanks Johannes_B for helping me out!

If you click on the underlined Dioxipe above, it'll lead you to a site where you can download the font. I've provided this link since I knew it's no well-known font and users may find it hard to find.

I know there are many Greek fonts around, yet this one is especially fine as it is a Didone and Didones are the first choice for quality Greek typesetting.

Everything works just out of the box using Linux Libertine O, but why is that? Why is polyglossia requesting a font with greek support, where Dioxipe obviously supports greek?

Let us call otfinfo on the font file to see which scripts are supported:

Code: Select all

$ otfinfo -s ufonts.com_dioxipe-opentype.otf 
latn		Latin

The font itself doesn't contain any information, that greek is supported.

Now, lets investigate with libertine, found in the fonts folder of my OS.

Code: Select all

$ otfinfo  -s /usr/share/fonts/opentype/linux-libertine/LinLibertine_R.otf
DFLT		Default
cyrl		Cyrillic
cyrl.SRB	Cyrillic/Serbian
grek		Greek
hebr		Hebrew
latn		Latin
latn.AZE	Latin/Azeri
latn.CRT	Latin/Crimean Tatar
latn.DEU	Latin/German
latn.MOL	Latin/Moldavian
latn.ROM	Latin/Romanian
latn.TRK	Latin/Turkish
math		Mathematical Alphanumeric Symbols

We can see, Linux Libertine provides the meta information that states, Yes, i do support greek.

Seems like an update of Dioxipe is in order.

[AleCes]

OK, I forgot to add accented characters in the Latin text: that's what annoys polyglossia; please, try throwing in something like

Code: Select all

\pagestyle{empty}
ᾶῆῶῦῖ\par
\textenglish{éèêë}\par
\fontspec{Latin Modern Roman}éèêë

and tell me if it works.

Thanks

OK, I got it now but the font doesn't seem to have any maintainer; anyhow the bug is trivial so I can definitely live with it.

Bump! Still waiting for answer to this: http://latex-community.org/forum/viewto ... 674#p89678

I somehow thought the issue would be resolved. And i right now don't know what is'nt running.
The following works just fine:

Code: Select all

\documentclass{book}
\usepackage{fontspec}
\defaultfontfeatures{Mapping=tex-text}
		%\setmainfont{Dioxipe}
\setmainfont{ufonts.com_dioxipe-opentype.otf}
\newfontfamily\greekfont{ufonts.com_dioxipe-opentype.otf}
\usepackage{polyglossia}
\setmainlanguage[variant=ancient]{greek}
\setotherlanguages{english}
\usepackage{xunicode}


\begin{document}

\pagestyle{empty}
ᾶῆῶῦῖ\par
\textenglish{abcd}\par
\fontspec{Latin Modern Roman} éèêë a e i 
\end{document}
