I am using book class with XeLaTeX. I want to change the toc counter 'I' (as shown here),

with a bullet but redefining the Roman alphabets will also change the alphabets in the main document (as shown in here)
which will then probably look like 'Part (bullet)' which makes no sense. Hence I want to separate the toc counter from the part definition.
MWE -
\documentclass[11pt]{book}
\raggedright
\usepackage[hidelinks]{hyperref}
\begin{document}
\frontmatter
\tableofcontents
\mainmatter
\part{The Part}
\chapter{The Chapter}
\section{The Section}
\end{document}
This is just an additional thought and not the main issue, but as I am also using hyperref and it automatically creates the outline for the pdf. As of now I am seeing the same entity which is in the part definition in the outline also.
This means if we replace the counter with a bullet it will be changed in the outline too, therefore I'll prefer a unicode-based bullet. Is it possible?




\numberline{I} The Partwhich was created by \part using \addcontentsline. You will have to modify \part to not do that. See https://tex.stackexchange.com/questions/490987/prevent-pagebreaks-before-and-after-part/490991?r=SearchResults&s=1|0.0000#490991 – John Kormylo May 17 '19 at 19:11
