# Lowercase font in title for book

I need to change the title of a section of my thesis (book), so that it shows nDCT instead of

What is the best way to do it? I tried using both \texorpdfstring{\MakeLowercase{n}DCT}{nDCT} and \MakeLowercase{n}DCT but none worked.

Here is a minimal working example:

\documentclass[openany,english,a4paper,12pt,twoside,titlepage]{book}
\usepackage{sectsty}

\partnumberfont{\fontfamily{ppl}\mdseries\scshape\Large}
\parttitlefont{\fontfamily{ppl}\mdseries\scshape\LARGE}
\chapternumberfont{\sffamily\mdseries\scshape\LARGE}
\chaptertitlefont{\fontfamily{ppl}\mdseries\upshape\Huge}
\sectionfont{\fontfamily{ppl}\bfseries\scshape\Large}
\subsectionfont{\fontfamily{ppl}\bfseries\scshape\normalsize}

\begin{document}
\makeatletter

\section{test}

\end{document}

• Why is everything uppercased in the first place? Please show us a minimal working example. – Johannes_B May 29 '16 at 12:54
• I just added it in the question – albus_c May 29 '16 at 13:02
• It is not uppercase, it is in small caps, as you declared; do \texorpdfstring{\textnormal{n}DCT}{nDCT} – egreg May 29 '16 at 13:06
• That works wonderfully – albus_c May 29 '16 at 13:11

You have declared \scshape and so the n is typeset in the small caps font.

For this particular case, do

\textnormal{nDCT}


or, maybe,

\texorpdfstring{\textnormal{nDCT}}{nDCT}


and you'll be OK.
