# How can I write an English document with a few words of Thai, Japanese, and Chinese?

I'm writing a document which is 99% English but needs a few words of other languages, including Thai, Japanese, and Chinese. I've had success with the latter two, but I'm stuck on Thai. Here's a MNWE:

\documentclass{article}

\usepackage{CJKutf8}

\begin{document}

Japanese: \begin{CJK}{UTF8}{min}結核\end{CJK}
Chinese: \begin{CJK}{UTF8}{bsmi}結核\end{CJK}
Thai: \begin{CJK}{UTF8}{gar}ไข้เด็งกี\end{CJK}   % <-- fail

\end{document}


Compiling this fails with:

LaTeX Font Warning: Font shape C70/gar/m/n' undefined
(Font)              using C70/song/m/n' instead on input line 9.

(/usr/local/texlive/2013/texmf-dist/tex/latex/cjk/texinput/UTF8/c70song.fd)
./b0rken.tex:9: Undefined control sequence.
try@size@range ...extract@rangefontinfo font@info
<-*>@nil <@nnil
l.9 Thai: \begin{CJK}{UTF8}{gar}ไข
้เด็งกี\end{CJK}  % <-- ...


Commenting out the "fail" line leads to successful compile with Japanese and Chinese characters where they should be in the output.

This is using MacTeX 2013. I do have the cjk and fonts-tlwg packages installed. I also have several c90* files present, including c90gar.fd and c90nrsr.fd.

I do need to stay with normal pdfTeX rather than XeTeX.

There's no CJK fonts in C70 encoding (Unicode) preinstalled for Thai in TeX Live. Fonts in C90 encoding cannot be used like that. –  Leo Liu Nov 16 '13 at 0:21
@Leo: OK. How can they be used? Are there C70 fonts I can install? –  Reid Nov 16 '13 at 4:07
The easiest way to use a few Thai words in LaTeX, is to include a graphic. I am not an expert on Thai. But the fonts for Thai are usually used in TIS 620 (input) encoding. Anyway, I'll try to provide a solution to explain how to use Thai fonts in C90 (font) encoding installed in TeX Live. –  Leo Liu Nov 16 '13 at 5:24

To use Thai fonts, we do not need to load CJK package, but babel package.

To use the fonts in C90 encoding, we can use thaicjk option of babel package.

\documentclass{article}

\usepackage[utf8x]{inputenc}

% English is the main language
\usepackage[thaicjk,english]{babel}

% Hack into CJKutf8 package for an option clash error
\makeatletter
\@namedef{opt@inputenc.sty}{utf8}
\makeatother
\usepackage{CJKutf8}

\begin{document}

Japanese: \begin{CJK}{UTF8}{min}結核\end{CJK}
Chinese: \begin{CJK}{UTF8}{bsmi}結核\end{CJK}
Thai: \foreignlanguage{thaicjk}{ไข้เด็งกี}

\end{document}


Or, we can also use the fonts in LTH encoding. In this case we need to use thai option of babel. See document of babel-thai.

\documentclass{article}

\usepackage[utf8x]{inputenc}

% English is the main language
\usepackage[thai,english]{babel}

% Hack into CJKutf8 package for an option clash error
\makeatletter
\@namedef{opt@inputenc.sty}{utf8}
\makeatother
\usepackage{CJKutf8}

\begin{document}

Japanese: \begin{CJK}{UTF8}{min}結核\end{CJK}
Chinese: \begin{CJK}{UTF8}{bsmi}結核\end{CJK}
Thai: \textthai{ไข้เด็งกี}

\end{document}

The second example works for me, thank you. (I didn't try the first.) –  Reid Nov 18 '13 at 21:11
