I'm writing a Finnish book using Pdflatex and I use Okular as my pdf-reader. Today I found that I can't use Ctrl+F to find the letters ä and ö. Is this a bug in Okular or am I doing something wrong?

Here is an example of a tex-file causing problems:

Code: Select all

\documentclass[10pt]{book}

\usepackage[utf8]{inputenc}
\usepackage[finnish]{babel}
\usepackage{blindtext}
\usepackage{siunitx}
\sisetup{output-decimal-marker = {,}}

\usepackage[a5paper]{geometry}
%\usepackage[a5paper, top=2in, bottom=1.5in, left=1in, right=1in]{geometry}
\usepackage{scrextend}
\changefontsizes{10.0pt}  % Change base font size

\usepackage{lettrine}
\usepackage{fancyhdr}

\usepackage{wasysym}
\pagestyle{fancy}
\fancyhf{} % clear all fields
\fancyhead[RO,LE]{\thepage}
\linespread{1.3}

\begin{document}
ÄÖäö
\end{document}

The problem is not within okular, but within the pdf files generated by TeX
with the Computer Modern font family (which does not contain umlauts so TeX
combines them from different glyphs). Even Adobe Reader has the same problem.

or https://bugs.kde.org/show_bug.cgi?id=131564

for umlauts etc. you have to use the right font encoding
\usepackage[T1]{fontenc}
% comment this out to use the EC fonts ... but lmodern is usually
% that what you want
