# error for special characters in \section in a classicthesis

Provided the following tex document using classicthesis, produces an error. How can I use direct input of special characters in \section in classicthesis?

I do not want to write e.g. \~{n} in the text, as it is not readable as easily as writing ñ.

\documentclass[10pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage[ngerman]{babel}
\usepackage[nochapters]{classicthesis}

\begin{document}
\section{umlauts å à É Ü }
text
\end{document}


The error is:

! Argument of \@firstofone has an extra }.
<inserted text>
\par
l.9     \section{umlauts å à É Ü }

!  ==> Fatal error occurred, no output PDF file produced!

The standard setup of classicthesis uses soul for spacing small caps; add the pdfspacing options that uses microtype features:

\documentclass[10pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage[ngerman]{babel}
\usepackage[nochapters,pdfspacing]{classicthesis}

\begin{document}

\section{umlauts å à É Ü}

text

\end{document}
