It sounds simple but I have a really heavy issue with the "ö ü ä ß" in Latex. I use a template from my university, i have a mac and i use TeXShop if that matters.
Within there is a packages.tex
with the following
(...)
\usepackage[T1]{fontenc} % Standard package for selecting font encodings
\usepackage{lmodern} % alternative Computer Modern-fonts for computer screens
\usepackage{textcomp} % LaTeX support for the Text Companion fonts
(...)
Also I have a thesis.tex
with
(...)
\usepackage[utf8]{inputenc} % Accept different input encodings
\usepackage{ifthen} % Conditional commands in LaTeX documents
(...)
Now I tried to use
\usepackage[ngerman]{babel}
as well as
\usepackage[applemac]{inputenc}
but unfortunately it doesn't work. The best case was another error "hyphenation flashed" or something.
\documentclass[
fontsize=12pt,
a4paper,
portrait,
oneside,
openright,
final,
titlepage,
onecolumn,
bibliography=totoc,
numbers=noenddot
]{scrbook}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[utf8]{inputenc}
\usepackage{ifthen}
\begin{document}
öä
\end{document}
Now I replaced
\usepackage[utf8]{inputenc}
with
\usepackage[applemac]{inputenc}
in the minimal working example above and it worked BUT in the other document it still doesn't work :( There it gives me the error (see picture)
