I'm using the kotex package in order to write in Korean in MikTex, and I found out that an error occurs on certain letters.

\documentclass{scrartcl}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{newtxtext}
\usepackage[nonewtxmathopt]{newtxmath}
\usepackage{kotex}

\begin{document}

\section{가}
나
\begin{enumerate}
\item ㄷ
\end{enumerate}

\end{document}


The error message is

Couldn't open uwmj.cfg'

No creation rule for font uwmj31. ! Font

• I just tried: unpack the uhc.tar.xz somewhere outside miktex, e.g.in a folder uhc. Then add the root folder as new root in miktex settings (the fonts folder should be the first subfolder). Add \pdfmapfile{=umj.map}` to your document or add the map via updmap. – Ulrike Fischer Jun 16 '17 at 14:12
