How to fix an error when using ko.TeX for typesetting Korean words?

I have a problem using ko.TeX for writing Korean words. I use MikTeX 2.9 with TeXworks as editor and pdfLaTeX as engine. I haven't used ko.TeX package, yet, so when I write Korean words (e.g. 남) as follows:

\documentclass{article}
\usepackage{kotex}
\begin{document}
남
\end{document}


TeXworks will install missing package (1) kotex-utf and then (2) kotex-plain during compilation but I'm getting this kind of error at the end:

! Missing \endcsname inserted.
\dhucs@serifhangulfont
1.4 남


Are we able to solve this particular problem?

• Do you really think people will be able to guess what's wrong on the basis of the information you've provided? Please help us to help you and add a minimal (non-)working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – cfr Jun 5 '14 at 1:17
• Your example is compilable (TL2013, lualatex+xelatex), but I'm missing some fonts. It works for me (TL2013, pdflatex). This is working for me but I'm not using ko.TeX and therefore I'm not solving your question: \documentclass{article} \usepackage{fontspec} \setmainfont{batang.ttc} \begin{document} 남 abc \end{document} – Malipivo Jun 5 '14 at 5:53
• The example compiles on TeX Live 2013; if I try with TeX Live 2012, the error File kotexutf.sty' not found pops out. I can't test on MiKTeX, but my feeling is that you should do an update of all your packages. – egreg Jun 5 '14 at 6:47
• I have reinstall MikTeX by using the latest version which covers all packages including kotex but the same error happens – bnbfreak Jun 5 '14 at 7:52
• @egreg I also install Tex Live 2013 but I have same errors. Is there any suggestion? maybe I miss something – bnbfreak Jun 5 '14 at 10:15

The kotex-utf package in MiKTeX omits a small file hfontspec.default. You can use cjk-ko instead of kotex-utf with putting [cjk] option to kotex, \usepackage[cjk]{kotex}`. Or make a 'hfontspec.default' file by yourself. Visit KTUG (Korean TeX Users Group) wiki site (in Korean).
