hyphenationline-breakingsectioning
I wonder if there is a way to avoid hyphenation of words in the title of a chapter.
I have tried \mbox but that makes the word run over the margin. I've also tried inserting a \\ in front of the word, but while this has the intended result on the chapter title page it has the unwanted side effect that the breakline also appears in the ToC.
Any ideas?
If you load the babel package with the [ngerman] option -- I'm taking a wild guess here that your document's language is German... -- LaTeX should have no problem hyphenating the word "universeller". See the MWE (minimum working example) below, which uses the LuaLaTeX format just to be able to use the nifty showhyphens package to indicate all hyphenation points with thin red vertical bars.
For sure do not place the word universeller into an \mbox unless you want to disable hyphenation. And don't provide the instruction \hyphenation{universeller} unless you, again, want to disable its hyphenation.
Furthermore, don't write "universeller" since with the ngerman option set, babel will interpret "u as a shortcut command for \"{u} and therefore typeset ü rather than "u. For the automatic use of language-appropriate quotation marks, do consider using the csquote package and its \enquote command, i.e., start writing \enquote{universeller}. (As @Dan has pointed out in a comment, the babel shortcut " gobbles up space after it. This explains why it's necessary to write ...seller" \ --- in the MWE to get a space between the end of the word and the em-dash. It also explains what you get the decidedly incorrect ”Fabianüniverseller...)
\documentclass[ngerman]{article}
\usepackage{fontspec}
\setmainfont[Ligatures=TeX]{Latin Modern Roman}
\usepackage{showhyphens,csquotes,babel}
\begin{document}
universeller
"universeller" \ --- This is a mistake!
``universeller'' --- U.S.-style quotation marks
\enquote{universeller} --- German-style quotation marks
\end{document}
Since you are using a KOMA class, the way to go is to use the tocstyle package:
The code:
\documentclass{scrreprt}
\usepackage[ngerman]{babel}
\usepackage[tocflat]{tocstyle}
\newtocstyle{raggedstyle}{%
\settocstylefeature[0]{entryhook}{\bfseries}
\settocstylefeature[0]{leaders}{\hfill}
\settocfeature{raggedhook}{\raggedright}
\settocfeature{spaceafternumber}{17pt}
}
\usetocstyle{raggedstyle}
\begin{document}
\tableofcontents
\chapter{Introduction}
\section{This kind of problem, that kind of problem, other ones and further considerations}
\section{More problems, even more problems, much worse than these, headline with no hyphenation and somo more text goes here for the example}
\end{document}
Refer to the package documentation for further adjustments.

If you want to have linebreaks in the chapter title, but not in TOC, use the optional argument for
\chapter:
