# Problems with diacritics in Ancient Greek

I need to type a special Greek character in LaTeX (I use XeLaTeX), but I don't know how do it.

\documentclass[14pt]{book}
\usepackage{titlesec}
\usepackage{polyglossia}
\usepackage{fontspec}
%\defaultfontfeatures{Ligatures=TeX}
\setmainlanguage{english}
\usepackage{hyperref}
%\usepackage{longtable}
\usepackage{textcomp}
\usepackage{expex}
\usepackage{epltxfn}
\usepackage{covington}
\makeatletter
\usepackage{url}
\pagenumbering{Roman}

\begin{document}

ῐ̔́

ῑ̔́

\twoacc['|\={ι}]

\twoacc[\'|\={ι}]

\end{document}


I want to type the first and the second (I just pasted it from Wikipedia), for the last two I use the package "convington", but I did not found where I can combine three diacritics (I just can do this with two!).

So, I want to know a way to put three (even more) diacritics.

• Does this answer your question? – Sandy G Feb 13 '18 at 3:29
• Unfortunately, the KadmosU font doesn't seem to be free. – egreg Feb 13 '18 at 8:30
• @SandyG , Unfortunately, I need to use a specific font for the package in question, I want to know if have a general method that works with all fonts that supports the symbol (Like: KadmosU, Linux Libertine O, New Athena Unicode e etc.) – Gergian Feb 13 '18 at 17:34
• @egreg I found this font at < fonts2u.com/kadmosu.font > and is free for personal use. Although is not open access :(. – Gergian Feb 13 '18 at 17:37

I'm afraid you have to find the correct tune up for each combination. The \kk macro adds kerning to fix the relative positions of the top accents.

\documentclass{article}
\usepackage{fontspec}

% since I don't have the font installed on my system, I placed it in the working directory
% use the following line if you have it among the system fonts

\DeclareRobustCommand{\combinedaccent}[2]{%
\leavevmode\vbox{\offinterlineskip
\ialign{\hfil##\hfil\cr
\hidewidth#1\hidewidth\relax\cr
\noalign{\vskip -1ex}
#2\cr
}%
}%
}
\newcommand{\dasia}{\raisebox{0.15ex}{\symbol{"A0}\symbol{"0314}}}
\newcommand{\psili}{\raisebox{0.15ex}{\symbol{"A0}\symbol{"0313}}}
\newcommand{\barys}{\symbol{"A0}\symbol{"0300}}
\newcommand{\oxys}{\symbol{"A0}\symbol{"0301}}
\newcommand{\kk}[1]{\kern#1em\relax}

\begin{document}

\combinedaccent{\dasia\oxys\kk{-0.15}}{\u{ι}}
\combinedaccent{\dasia\oxys\kk{-0.15}}{\={ι}}
\combinedaccent{\dasia\oxys\kk{-0.15}}{\={ι}}
\combinedaccent{\kk{0.15}\psili}{\={ι}}
\combinedaccent{\kk{0.25}\oxys}{\={ι}}

\end{document}


• Thank you for your reply, but I just paste your answer but did not work in my XeLaTeX. He said: "Archive not found", and appeared white pdf... I did not what happen... – Gergian Feb 14 '18 at 0:41
• @BozenoBozilson I used [Extension=.ttf,Path=./] to adjust for my system. You probably have KadmosU installed as a system font so you don't need that part. – egreg Feb 14 '18 at 0:43
