I'm using the package polyglossia and I'm building the index with imakeidx. One index, which contains greek words, does not follow the correct alphabetical order. How could I do to get a correct alphabetical order? Here is an MWE:

\documentclass{article}

\usepackage{fontspec}
\setmainfont{times.ttf}
\newfontfamily\greekfont{times.ttf}

\usepackage{imakeidx}
\usepackage{polyglossia}
\setmainlanguage{english}
\setotherlanguage[variant=ancient]{greek}

\makeindex[name=1]

\begin{document}

\selectlanguage[variant=ancient]{greek}{ἀγαθός, καλός, δεινός, μείγνυμι}


\index[1]{ἀγαθός} 
\index[1]{καλός}
\index[1]{δεινός} 
\index[1]{μείγνυμι}

\printindex[1]

\end{document}

The problem is caused because the symbol over α meddles with the sorting algorithm. A possible solution would be to use \index[1]{αγαθος@ἀγαθός} instead of \index[1]{ἀγαθός}. In this way the entry will appear as ἀγαθός but will be sorted as αγαθος. Greetings from Greece!

\documentclass{article}
\usepackage{fontspec}
\setmainfont{times.ttf}
\newfontfamily\greekfont{times.ttf}
\usepackage{imakeidx}
\usepackage{polyglossia}
\setmainlanguage{english}
\setotherlanguage[variant=ancient]{greek}
\makeindex[name=1]
\begin{document}
\selectlanguage[variant=ancient]{greek}{ἀγαθός, καλός, δεινός, μείγνυμι}
\index[1]{αγαθος@ἀγαθός}
\index[1]{καλός}
\index[1]{δεινός} 
\index[1]{μείγνυμι}
\printindex[1]
\end{document}
