"pxbabel" unable to compile Korean characters under pTex due to font

Question

some backgrounds:

• System: OS X 10.11.6 (El Capitan)
• MacTex version: 2016
  
• Software: TexShop (pTex configured exactly as here)

It is a feature of pxbabel that it provides multiple language support for pTex and upTex, such as in Chinese, Koreans, Russian, etc, through \foreignlanguge{language}{text}, and below is a document that is supposed to compile successfully.

\documentclass[a4paper,uplatex]{jsarticle}
\usepackage[english]{babel}
\usepackage[main=japanese]{pxbabel}
\begin{document}
\foreignlanguage{korean}{내가득합니다}
\end{document}

When trying to compile, however, the system returned with the following error message:

This is ptex2pdf[.lua] version 0.8.

From "Could not locate a virtual/physical font for TFM "uphysmjm-h"" It seems that the code works but the system was unable to find the font for the Korean characters.

From other sources, I know that pxbabel is using this Korean font: http://kldp.net/unfonts/

I have spent hours looking at the [/usr/local/texlive] without any clue... is there any way that I can help the system connect between the pxbabel package to the Korean fonts it needs?

Answer 1

Pxbabel does nothing about "physical" font settings. So, you have to tell dvipdfmx which font you are going to use.

The easiest way to do that may be:

\documentclass[a4paper,uplatex]{jsarticle}
\usepackage[english]{babel}
\usepackage[main=japanese]{pxbabel}
\AtBeginDvi{\special{pdf:mapline uphysmjm-h UniKS-UTF16-H UnBatang.ttf}}
\AtBeginDvi{\special{pdf:mapline uphysmjm-v UniKS-UTF16-V UnBatang.ttf}}
\AtBeginDvi{\special{pdf:mapline uphygt-h UniKS-UTF16-H UnDotum.ttf}}
\AtBeginDvi{\special{pdf:mapline uphygt-v UniKS-UTF16-V UnDotum.ttf}}
\begin{document}
\foreignlanguage{korean}{내가득합니다}%
\foreignlanguage{korean}{\textgt{내가득합니다}}
\end{document}

Of course, first you have to install these fonts (.ttf) into your $TEXMFLOCAL (e.g. /usr/local/texlive/texmf-local/fonts/truetype/unfonts), and run sudo mktexlsr.

Update (2017-01-14): Norbert and I developed new map files for Chinese and Korean fonts, and the changes has been applied to TeX Live r42939--r42951. Now Korean fonts default to baekmuk, so the error will never happen after the update of your installation. Also, you can change the default font settings from baekmuk to unfonts by

(sudo) updmap-sys --setoption koEmbed unfonts

command.
