# How to Recover my Bold SF Fonts

I was inspired by this link to try EulerVM with tgpagella packages:

How do I set LaTeX to use AMS Euler for text and maths?

But when this is used with \documentclass{scrbook}, it seems that my bold-faced sans serif fonts are overwritten. Not only with the sections and subsections and whatnot, but in other areas that I have designated to have a bold sans serif font such as my enumi counters.

Can someone help me bring the sans serif bold back in computer modern but with a fully functioning use of EulerVM with tgpagella packages?

I apologize in advance if I am not properly following conventions here.

\documentclass{scrbook}
\usepackage{tgpagella}
\usepackage{eulervm}
\usepackage[T1]{fontenc}
\usepackage{mathrsfs}
\usepackage{enumerate}
\usepackage{microtype}

\def\theenumi{\textsf{\textbf{\arabic{enumi}}}}
\def\theenumii{\textsf{\textbf{\alph{enumii}}}}

\begin{document}

\chapter{A Chapter}

\section{A Section}

\subsection{A Subsection}

Some numbers

\begin{enumerate}
\item The item should be bold sans.

\item It seems that they are being over written somewhere

\item I also get this: Warning: Font shape T1/cmss/b/n' undefined
(Font)  using T1/cmss/m/n' instead on input line 14.
\end{enumerate}

\end{document}

• Can you add a minimal working example (MWE) that illustrates your problem? It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – egreg Jun 5 '13 at 18:10
• I am such a novice? Can some one edit my comment into a nice MWE box? My humble apologies. – RobertD Jun 5 '13 at 20:36
• I reverted your last edit: it's better to have the code rather than in a comment. – egreg Jun 5 '13 at 20:37

## 1 Answer

The tgpagella package does

\renewcommand{\bfdefault}{b}


where the original value is bx. Since the standard Computer Modern Sans font don't know of a b series, but only a bx series, the internal substitution mechanism chooses medium series.

You can correct this in two ways.

1. Load lmodern before tgpagella, because the Latin Modern Sans fonts know about a b series

2. Do \renewcommand{\bfdefault}{bx} after loading tgpagella.

The fonts you get are slightly different. Take your pick. In the code below I load only the font packages, add the others you need.

## Method 1

\documentclass{scrbook}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{tgpagella}
\usepackage{eulervm}
\usepackage{mathrsfs}
\usepackage{microtype}


## Method 2

\documentclass{scrbook}
\usepackage[T1]{fontenc}
\usepackage{tgpagella}
\renewcommand{\bfdefault}{bx}
\usepackage{eulervm}
\usepackage{mathrsfs}
\usepackage{enumerate}
\usepackage{microtype}
