Chapter heading with two languages and two fonts

I want the option of adding some Hebrew (including a different font) to my chapter heading but otherwise keep the default chapter style used in scrbook. Most chapter headings will contain only English, but occasionally I would like to have both English AND Hebrew in the chapter heading. I have commented out things I tried that didn't work.

Though \usepackage{libertine} allows the Hebrew to appear, I do not want to use it because that will change everything to a libertine font, and I want to retain the default chapter heading font in English.

MWE:

%XeLaTeX
\documentclass[11pt]{scrbook}

\usepackage{polyglossia}
\setdefaultlanguage{english}
\setotherlanguage{hebrew}
\newfontfamily\hebrewfont[Script=Hebrew]{Linux Libertine O}
\newfontfamily\englishfont{Linux Libertine O}

\begin{document}

\chapter{Hebrew-1 (עברית)}
%\chapter{Hebrew-2 (\texthebrew{עברית})}
%\chapter{Hebrew-3 (\begin{hebrew}עברית\end{hebrew})}
%\chapter{Hebrew-4\selectlanguage{hebrew}(עברית)}

\end{document}


In case you were wondering, עברית is just the Hebrew word for "Hebrew".

Chapter titles are typeset in sans serif in scrbook. So you need to define also a sans serif hebrewfont:

\documentclass[11pt]{scrbook}
%\usepackage{libertine}
\usepackage{polyglossia}
\setdefaultlanguage{english}
\setotherlanguage{hebrew}
\newfontfamily\hebrewfont[Script=Hebrew]{Linux Libertine O}
\newfontfamily{\hebrewfontsf}[Script=Hebrew]{Linux Libertine O}%or whatever
\newfontfamily\englishfont{Linux Libertine O}

\begin{document}

\chapter{Hebrew-1 \texthebrew{(עברית)}}
%\chapter{Hebrew-2 (\texthebrew{עברית})}
%\chapter{Hebrew-3 (\begin{hebrew}עברית\end{hebrew})}
%\chapter{Hebrew-4\selectlanguage{hebrew}(עברית)}

\end{document}


• I want the Hebrew in the chapter heading to be a serif font. How would I set the Hebrew to be serif in the chapter while leaving the English as sans serif? – AML May 23 '18 at 18:14
• ? I don't understand, this is libertine and it is a serif font. – Ulrike Fischer May 23 '18 at 18:17
• Good point. I was simply confused by the combination of \hebrewfontsf (sans serif) with Linux Libertine O (serif), but now I understand. – AML May 23 '18 at 18:20
