I am using XeLaTeX because Unicode. What am I doing wrong? I do not see the inputenc dependency (guess indirect?), and have no idea how to proceed:
\documentclass[a4paper, twoside]{book}
\usepackage[english, arabic, russian, german]{babel}
\usepackage{xeCJK}
\begin{document}
mwe
\end{document}
! Package inputenc Error: inputenc is not designed for xetex or luatex. (inputenc) only UTF-8 supported.
Or is polyglossia not deprecated anymore (now there is a 2019 doc)?
