# Differences between libertine and libertinus packages regarding pdfTeX

Until now I did not switch to LuaTeX and prefer pdfTeX, because it's faster. Since some years I've been using the old libertine-legacy package, e.g. because I need the command \libertingeGlyphand \biolinumGlyph, which print a certain glyph.

On the long run I'll have to dismiss libertine-legacy and replace it either with libertine or the fork libertinus.

Can somebody point out differences between these two packages with regard to pdfTeX, which I'm using?

And how I can use e.g. roman numbering without the \libertineGlyphcommand, which used to provide the roman numbering glyphs from libertine in an example like this:

\documentclass{scrartcl}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{libertine}

\begin{document}

I'd like to use a Roman Number, but how to do without \libertineGlyph{Oneroman}

\end{document}


Or how can I define the two mentioned commands, either with libertine or libertinus-package?

• I have no idea about fonts, but it seems to me that libertine-legacy defines many additional font families to get around the 256(?) character limit per family. So you can access these special characters by being internally re-routed to another font family. The new libertine package does not do these shenanigans and so you can only access the 256 characters per family. – moewe May 5 '18 at 7:05
• Since last september there is also a libertinus-type1 package on CTAN. Herbert Voss has written a wrapper package libertinus. – campa Nov 28 '18 at 10:38

• Yes, I looked into the package libertinus and found only *.otf files. Whenever I find time I'll dive into the libertine.sty of the new libertine package and try to find out, if the \libertineGlyphcommand is included or how to define it. – Keks Dose May 4 '18 at 15:50
