The issue: Using imakeidx for indexing in greek language the result is not in the right alphabetical order. I tried to use xindy-package also, but with no success. The right alphabetical order in greek is

ΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩ

but as you may see In the minimal example below, the index is not in the right alphabetical order (after compiling). Any help will be greatfully appreciated!

\documentclass[10pt]{article}
\usepackage[english, greek]{babel}
\usepackage[iso-8859-7]{inputenc}
\usepackage{gfsbodoni}
 \usepackage{imakeidx}

 \makeindex[program=makeindex,columns=2,title=Ευρετήριο όρων,   
  intoc=true,options={-s index_style.ist}]

 \usepackage{hyperref}

  \begin{document}
   Α\index{α}
   Β\index{β}
   Γ\index{γ}
   Δ\index{δ}
   Ε\index{ε}
   Ζ\index{ζ}
   Η\index{η}
   Θ\index{θ}
   Ι\index{ι}
   Κ\index{κ}
   Λ\index{λ}
   Μ\index{μ}
   Ν\index{ν}
   Ξ\index{ξ}
   Ο\index{ο}
   Π\index{π}
   Ρ\index{ρ}
   Σ\index{σ}
   Τ\index{τ}
   Υ\index{υ}
   Φ\index{φ}
   Χ\index{χ}
   Ψ\index{ψ}
   Ω\index{ω}

   \printindex

   \end{document}

...and the index_style.ist

headings_flag 1
heading_prefix "{\\large\\sffamily\\bfseries "
heading_suffix "}\\nopagebreak\n"
delim_0 " \\dotfill "
delim_1 " \\dotfill "
delim_2 " \\dotfill "

MakeIndex does not cope with letters beyond ASCII.

Run with -shell-escape. I'm not sure Xindy supports iso-8859-7.

\documentclass[10pt]{article}
\usepackage[english, greek]{babel}
\usepackage[utf8]{inputenc}
\usepackage{gfsbodoni}
\usepackage[xindy]{imakeidx}
\usepackage[unicode]{hyperref}

\makeindex[columns=4,title=Ευρετήριο όρων,intoc=true,options=-L greek -C utf8]

\AtBeginDocument{%
  \let\imakeidxindex\index
  \renewcommand{\index}[2][]{%
    \if\relax\detokenize{#1}\relax
      \imakeidxindex{\detokenize{#2}}%
    \else
      \imakeidxindex[#1]{\detokenize{#2}}%
    \fi
  }%
}

\begin{document}

Α\index{α}
Β\index{β}
Γ\index{γ}
Δ\index{δ}
Ε\index{ε}
Ζ\index{ζ}
Η\index{η}
Θ\index{θ}
Ι\index{ι}
Κ\index{κ}
Λ\index{λ}
Μ\index{μ}
Ν\index{ν}
Ξ\index{ξ}
Ο\index{ο}
Π\index{π}
Ρ\index{ρ}
Σ\index{σ}
Τ\index{τ}
Υ\index{υ}
Φ\index{φ}
Χ\index{χ}
Ψ\index{ψ}
Ω\index{ω}

\printindex

\end{document}

I used four columns just to make a shorter image.

  • In both utf8 and iso-8859-7 it works, but I get a bit different result, i.e. the capital letters not appearing, but the alphabetical order is correct. I don't know why this happens. Nevertheless, thank you. P.S. what is -shell-escape? Commented Aug 3, 2019 at 19:09
