Problem with typesetting maths content in an unusual font in beamer

Question

I want to typeset math in different font called Antykwa Torunska, which supports maths. Unfortunately, when using it in beamer the math font is switched to the standard math font of beamer. How can I change this behaviour?

Here is a minimal example:

\documentclass{beamer}
% Mathekram:
\usepackage{amssymb, amstext, amsmath}
% Font:
\usepackage[math]{anttor}
\usepackage[T1]{fontenc}


\begin{document}

\begin{frame}{Testframe}
   This is fine: 1234567890, \textit{x}, \textit{p}, \textit{t}\\
   This is not fine: $1234567890$, $x$, $p$, $t$
\end{frame}

\end{document}

When I change beamer to article it works fine.

Answer 1

You should add \usefonttheme{professionalfonts} to your preamble or use the professionalfonts class option, in order to suppress any font replacements performed by beamer.

Answer 2

I think you just need to add the [professionalfont] option to your \documentclass command. See section 18.1 of the beamer documentation for details.
