# Issues with nesting \textbf and \textit

I am trying to format a text so that it is bold and italic at the same time. I am doing this by nesting the \textbf and \textit commands, what should be no problem according to "Correct" way to bold/italicize text?. However, in the resulting pdf the text appears just bold.

\documentclass[10pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{a4wide}
\usepackage{graphicx}
\usepackage{setspace}
\usepackage[font=small]{caption}
\usepackage{multicol}
\usepackage{etoolbox}
\usepackage{url}
\usepackage{enumitem}

\patchcmd{\chapter}{\if@openright\cleardoublepage\else\clearpage\fi}{}{}{}
\patchcmd{\quote}{\rightmargin}{\leftmargin 1em \rightmargin}{}{}

\renewcommand{\thesection}{\Roman{section}}
\renewcommand{\familydefault}{\sfdefault}
\renewcommand{\baselinestretch}{1.0}

\begin{document}
\begin{multicols}{2}

\textbf{
\textit{Keywords}\textemdash Service oriented Architecture, Service, Component, Functional Safety
}

\end{multicols}{2}
\end{document}


I don't whether this is of relevance, but this code is inside a multicolumn environment.

• Full minimal example please. We'd like to know your preamble. Also is there any warnings in your log file? Might be that the sans serif font you are using does not provide a bold italic version. – daleif May 28 '15 at 12:40
• not related to the question, but this would look much nicer ratted right. – barbara beeton May 28 '15 at 14:36

LaTeX warns to the terminal and log file

LaTeX Font Warning: Font shape OT1/cmss/bx/it' undefined
(Font)              using OT1/cmss/bx/n' instead on input line 24.


which says that the computer modern fonts don't have sans serif bold italic, so it is going to use sans serif bold normal shape instead.

\usepackage{lmodern}


selects a similar but different font set that does have this shape.
