I recently changed the page numbers to duodecimal ones (see here). The package makeidx didn't like that at all. In fact my index isn't written at all anymore:

done (0 entries accepted, 341 rejected). Nothing written in
Kyroledorn Yartolikor.ind. Transcript written in Kyroledorn
Yartolikor.ilg.

Everything worked before the change, so this is the only problem here. Other questions imply that makeidx has some restrictions regarding alterations in the page numbers but I didn't find a solution for this problem. Any ideas?

As a code example I added an index into the code sample from the question above, exactly as I did it in my other file.

documentclass[11pt,a4paper,final]{book}

    usepackage[left=2cm,right=2cm,top=2cm,bottom=2cm]{geometry}

    usepackage{makeidx}

    makeindex

    usepackage{graphicx} % I need this to rotate my numbers...

    usepackage{xparse} % this is the magic package...

    ExplSyntaxOn % for the missing numbers after 9 the package uses "a" and "b",

                  % but I want to use "↊" and "↋" as defined by the Dozenal

                  % Society of Great Britain. The following lines do that for me:



    NewDocumentCommand{basetwelve}{m}

      { duodec_convert:n { #1 } }



    tl_new:N l_duodec_string_tl

    cs_new_protected:Npn duodec_convert:n #1

      {

       tl_set:Nx l_duodec_string_tl { int_to_base:nn { #1 } { 12 } }

       tl_replace_all:Nnn l_duodec_string_tl { a } { rotatebox[origin=c]{180}{2} }

        % I rotate the numbers, because standard fonts don't contain ↊ and ↋.

       tl_replace_all:Nnn l_duodec_string_tl { b } { rotatebox[origin=c]{180}{3} }

       tl_use:N l_duodec_string_tl

     }

    ExplSyntaxOff 



    renewcommand{thepage}{basetwelve{arabic{page}}}

    renewcommand{thepart}{basetwelve{arabic{part}}}

    renewcommand{thechapter}{basetwelve{arabic{chapter}}} 

     % No problems so far...

     % This is how you get numbering formatted as chapter.section:

    renewcommand{thesection}{thechapter.basetwelve{arabic{section}}} 

    renewcommand{thesubsection}{thesection.basetwelve{arabic{subsection}}}

     % Dont put thechapter here, it is already contained in thesection!!!

    renewcommand{thefigure}{basetwelve{arabic{figure}}} 

     % As I told you, I wanted to change the figcaptions too. 

     % But I don't need the chapter's number here.

    renewcommand{labelenumi}{basetwelve{arabic{enumi}}.} 

     % And this is my first dozenal enumeration with a dot behind the number.



     %let's see, if it works:

    begin{document}

    part{Quick demonstration}

    chapter{Here we go!}

    Just scroll down...

    chapter{I}

    chapter{need}

    chapter{lots}

    Whoops, nearly there...

    newpage

    On this and on the following page you see the dozenal page numbers! index{dozenal page number}

    chapter{of}

    See? It works! index{working!}

    chapter{pages}

    chapter{and}

    chapter{chapters}

    chapter{for}

    chapter{dozenal}

    This is the dozenal number  rotatebox[origin=c]{180}{2}, equal to $ 10_{(10)} $.

    chapter{numbers.}

    This is the second dozenal number: rotatebox[origin=c]{180}{3}, it is just a turned 3 and equal to $ 11_{(10)} $.

    section{What are these symbols?!}

    I use fonts like Times New Roman, they have symbols index{symbols} like rotatebox[origin=c]{180}{2} and rotatebox[origin=c]{180}{3} integrated as Unicode glyphs U+218A and U+218B. They are just rotated numbers too, basicly. These numbers are defined by the Dozenal Society of Great Britain and I like them. If you complie with XeLaTeX you can just copy and paste these signs: ↊ and ↋ (in this font they will probably be invisible).



    section{Why so many chapters?}

    I need more than 12 pages and chapters for the numbers index{numbers}  rotatebox[origin=c]{180}{2} and rotatebox[origin=c]{180}{3} to appear.



    section{Enumeration}

    begin{enumerate}

    item Just

    item a

    item very

    item short

    item demonstration

    item of

    item a

    item dozenal

    item enumeration

    item for

    item you

    item to

    item admire.

    end{enumerate}

    section{Just a random section}

    subsection{with a subsection}

    subsubsection{and a subsubsection}

    These all work just finde with dozenal numbers aswell but I think the code is already long enough. And as you see, subsubsections usually don't have numbers at all.

    printindex 

    end{document}
