Libertine newtxmath and text (oldstyle) figures in headers
This seems to work:
\documentclass[12pt]{memoir}
\usepackage[T1]{fontenc}
\usepackage[oldstyle]{libertine}
\makeatletter
\renewcommand*\libertine@figurestyle{LF}
\makeatother
\usepackage[libertine]{newtxmath}
\makeatletter
\renewcommand*\libertine@figurestyle{OsF}
\makeatother
\begin{document}
\section{foo 123 bar}
Text figures: 0123456789 \textbf{0123456789}
\par\noindent
Math figures: $0123456789$
\end{document}
For the current newtxmath
, don't use the osf
option before \usepackage[libertine]{newtxmath}
but add the following 4 lines immediately after:
\makeatletter
\def\libertine@figurestyle{OsF} %affects \libertine macro
\makeatother
\renewcommand*{\rmdefault}{LinuxLibertineT-OsF} % for normal text
It's in newtxdoc.pdf
.
The package Libertine
(as of the version published on february 11, 2014) provides the \useosf
command, which, if used after loading the math font, sets old-style figures only for text (including headers).
