Linux Libertine: Change Numeral Set

In LuaLaTeX and XeLaTeX you can specifiy font features with the fontspec package.

The Numbers/RawFeature features are

• Lining and Uppercase/lnum: normal/majuscule figures
• OldStyle and Lowercase/onum: medieval/minuscule figures
• Proportional/pnum
• Monospaced/tnum (t stands for tabular)
• SlashedZero/zero: gives slashed 0

You can activate these features with either

\addfontfeatures{Numbers={OldStyle,Proportional}}

or

\addfontfeatures{RawFeature=+onum;+pnum}

If you use the libertineotf package (which also provides shortcuts to change these settings in-document, cf the package manual), you can give these arguments directly as package options:

\usepackage[
    libertine={Ligatures=TeX,RawFeature=+onum;+pnum},
     biolinum={Ligatures=TeX,RawFeature=+onum;+pnum},
         mono={Scale=MatchLowercase,RawFeature=+zero}]
    {libertineotf} 

If you don't you can still set the options directly when specifying the fonts:

\setmainfont[RawFeature=+onum;+pnum]{Linux Libertine O}
\setsansfont[RawFeature=+onum;+pnum]{Linux Biolinum O}

---

Here is an exemplary code:

\documentclass{article}
\usepackage{fontspec}
\setmainfont{Linux Libertine O}
\def\numbers{0123456789}
\begin{document}
    \begin{tabular}{lrrr}
        \textbf{Normal Zero} &                                              Monospaced &                                              Proportional &  \\
        Lining               &   \addfontfeatures{Numbers={Lining,Monospaced}}\numbers &  \addfontfeatures{Numbers={Lining,Proportional}} \numbers &  \\
        OldStyle             & \addfontfeatures{Numbers={OldStyle,Monospaced}}\numbers & \addfontfeatures{Numbers={OldStyle,Proportional}}\numbers &  \\
    \end{tabular}

    \vspace{1ex}
    \addfontfeatures{Numbers=SlashedZero}
    \begin{tabular}{lrrr}
        \textbf{Slashed Zero} &                                              Monospaced &                                              Proportional &  \\
        Lining                &   \addfontfeatures{Numbers={Lining,Monospaced}}\numbers &  \addfontfeatures{Numbers={Lining,Proportional}} \numbers &  \\
        OldStyle              & \addfontfeatures{Numbers={OldStyle,Monospaced}}\numbers & \addfontfeatures{Numbers={OldStyle,Proportional}}\numbers &  \\
    \end{tabular}
\end{document}

Use Numbers=OldStyle:

\setmainfont[Numbers={OldStyle}]{Linux Libertine O}

From fontspec's doc, table 4:

 Feature         Option             Tag

 Numbers =      Uppercase/Lining     lnum
                Lowercase/OldStyle   onum
                Proportional         pnum
                Monospaced           tnum
                SlashedZero          zero
                Arabic               anum

\documentclass{article}
\usepackage[libertine={Ligatures=TeX,RawFeature=+onum}]{libertineotf}
\begin{document}

0123456789

\end{document}

or also for the sans serif Biolinum

\usepackage[libertine={Ligatures=TeX,RawFeature=+onum},
            biolinum={Ligatures=TeX,RawFeature=+onum}]{libertineotf}
