Encoding stuff based on the internal font machinery of TeX (letters with catcode 11 or 12, ligatures) does not work, because the strings don't reach TeX's stomach. \end{quote} % The \emph{lgrx} bundle allows input of Greek characters that work in both, the main document as well as in PDF strings (e.g. bookmarks). \section{Transcription: \TextGreek{logos}, \foreignlanguage{greek}{logos}} \textbackslash{}textgreek + LGR transcription or Greek language (babel) + LGR transcription: In the PDF-bookmark are Latin letters instead of Greek ones. \section{Macros: \textlambda\textomicron\textgamma\textomicron\textvarsigma{}, \lambda\omicron\gamma\omicron\varsigma{}, λογος} textalpha package with \textbackslash{}textgreek* macros, alphabeta package with \textbackslash{}alpha ... \textbackslash{}Omega macros, and literal Greek Unicode characters (using \textbackslash{}textgreek* macros internally). Works, if the "unicode" option is given to hyperref. (With xpdf, Greek letters are not shown in PDF bookmarks.) The generic short macros from the \emph{alphabeta} package result in hyperref warnings: \begin{verbatim} Package hyperref Warning: Token not allowed in a PDF string (Unicode): (hyperref) removing `\TextOrMath ' on input line 44. Package hyperref Warning: Token not allowed in a PDF string (Unicode): (hyperref) removing `\mathlambda' on input line 44. \end{verbatim} However, the warnings can be ignored and the output is OK. \section{% Kerning: \textAlpha\textUpsilon\textLambda{} \TextGreek{\textAlpha\textUpsilon\textLambda} \foreignlanguage{greek}{\textAlpha\textUpsilon\textLambda}% } Kerning is impossible if the font encoding is switched for every single character. Wrap the Greek part in a command switching to LGR font encoding to fix this, either \verb+\TextGreek{...}+ (with package textalpha) or \verb+\foreignlanguage{greek}{...}+ (with babel). % letters of the Greek and Coptic Unicode Block supported by LGR: \newcommand{\GreekAndCoptic}{ʹ͵ͺ; ΄ ΅ Ά·ΈΉΊΌΎΏΐΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩΪΫϘϚϜϠ} \newcommand{\greekandcoptic}{άέήίΰαβγδεζηθικλμνξοπρςστυφχψωϊϋόύώϙϛϝϟϡ} \section{Testing supported Unicode chars} \subsection{\GreekAndCoptic} \subsection{\greekandcoptic} \subsection{ἀἁἂἃἄἅἆἇἈἉἊἋἌἍἎἏ ἐἑἒἓἔἕἘἙἚἛἜἝ} \subsection{ἠἡἢἣἤἥἦἧἨἩἪἫἬἭἮἯ ἰἱἲἳἴἵἶἷἸἹἺἻἼἽἾἿ} \subsection{ὀὁὂὃὄὅὈὉὊὋὌὍ ὐὑὒὓὔὕὖὗὙὛὝὟ} \subsection{ὠὡὢὣὤὥὦὧὨὩὪὫὬὭὮὯ ὰάὲέὴήὶίὸόὺύὼώ} \subsection{ᾀᾁᾂᾃᾄᾅᾆᾇᾈᾉᾊᾋᾌᾍᾎᾏ ᾐᾑᾒᾓᾔᾕᾖᾗᾘᾙᾚᾛᾜᾝᾞᾟ} \subsection{ᾠᾡᾢᾣᾤᾥᾦᾧᾨᾩᾪᾫᾬᾭᾮᾯ ᾰᾱᾲᾳᾴᾶᾷᾸᾹᾺΆᾼ᾽ι᾿} \subsection{῀῁ῂῃῄῆῇῈΈῊΉῌ῍῎῏ ῐῑῒΐῖῗῘῙῚΊ῝῞῟} \subsection{ῠῡῢΰῤῥῦῧῨῩῪΎῬ῭΅` ῲῳῴῶῷῸΌῺΏῼ´῾} \section{Conclusion} For Greek text parts in section headers use either literal Unicode characters or macros. For proper kerning in the main document, combine this with the \verb+\textgreek+ or \verb+\foreignlanguage{greek}+ macros. \end{document}
