I am setting up a document for PhD thesis in Greek and I have troubles when I am typing Greek characters in \section{}, \part{}, \chapter{}. When it compiles the section turns out fine although I get many hyperref warnings, however, when it comes to parts and chapters it compiles unrecognized characters.

For the Minimal Working Example (MWE) the warnings I get are like this:

Package hyperref Warning: Token not allowed in a PDF string (PDFDocEncoding): (hyperref) removing `\begingroup' on input line 17.

The error I get is:

! Package ucs Error: Unknown Unicode character 909 = U+038D,

(ucs) possibly declared in uni-3.def.

(ucs) Type H to see if it is available with options.

See the ucs package documentation for explanation.

Type H for immediate help.

...

l.17 \part{Τίτλος μέρους}

? h

Character's name unknown

Character is not defined in uni-*.def files.

Enter I! to define the glyph.

This is my MWE:

\documentclass[12pt]{thesis}

\usepackage[LGR]{fontenc}
\usepackage[utf8x]{inputenc}
\usepackage[english,greek.polutoniko]{babel}
\usepackage{color}
\usepackage[colorlinks=true, pdfstartview=FitV, linkcolor=blue, citecolor=blue, urlcolor=black]{hyperref}

\newcommand{\en}{\selectlanguage{english}}
\newcommand{\gr}{\selectlanguage{greek}}

\begin{document}

\tableofcontents

\part{Τίτλος μέρους}

\chapter{Τίτλος κεφαλαίου}

\section{Τίτλος}

\chapter{\en Chapter name}

\end{document}

This is part of the output:

Part 1 and name of part1

chapter name and section name

    Use utf8 instead of utf8x and remove \usepackage[LGR]{fontenc}. Where is the thesis class available?

  • I have done what you said, still the same. I am not sure what you mean by "where is the thesis class available?". It is under texmf/tex/latex/thesis.

    Oh, the one that comes with MiKTeX?

The thesis class you're using has been unsupported since 1996.

The main problem is that it uses \uppercase instead of \MakeUppercase in several places. Another problem is using utf8x which is unmaintained and buggy.

A minor problem is hyperref not understanding \acctonos and \textfinalsigma, which can be solved by adding support for it.

\documentclass[12pt]{thesis}

\usepackage[english,greek.polutoniko]{babel}
\usepackage{color}
\usepackage{etoolbox}

%%% fix the faulty bits of thesis.cls
\makeatletter
\patchcmd{\@part}{\uppercase}{\MakeUppercase}{}{}
\patchcmd{\@spart}{\uppercase\expandafter}{\MakeUppercase}{}{}
\patchcmd{\@makechapterhead}{\uppercase}{\MakeUppercase}{}{}
\patchcmd{\@makechapterhead}{\uppercase}{\MakeUppercase}{}{}
\patchcmd{\@makechapterhead}{\uppercase}{\MakeUppercase}{}{}
\patchcmd{\@makechapterhead}{\uppercase}{\MakeUppercase}{}{}
\patchcmd{\@makeschapterhead}{\uppercase\expandafter}{\MakeUppercase}{}{}
\makeatother

\usepackage[
  unicode,
  colorlinks=true,
  pdfstartview=FitV,
  linkcolor=blue,
  citecolor=blue,
  urlcolor=black,
]{hyperref}

\DeclareTextCompositeCommand{\acctonos}{PU}{\textalpha}{\9003\254}
\DeclareTextCompositeCommand{\acctonos}{PU}{\textepsilon}{\9003\255}
\DeclareTextCompositeCommand{\acctonos}{PU}{\texteta}{\9003\256}

\DeclareTextCompositeCommand{\acctonos}{PU}{\textomega}{\9003\316}
\DeclareTextCommand{\textfinalsigma}{PU}{\9003\302}

\begin{document}

\tableofcontents

\part{Τίτλος μέρους}

\chapter{Τίτλος κεφαλαίου}

\section{Τίτλος}

\begin{otherlanguage}{english}
\chapter{Chapter name}

\end{otherlanguage}

\end{document}

If a chapter is in English it's better to use otherlanguage around it.
