Dear LaTeX CJK listers,
I read it from
Werner's <Unicode Support in the CJK Package> in
The Asian Journal of TEX, Volume 2, No. 1, April 2008
that using CJKutf8 and cmap packages along with pdflatex can generate a PDF
where we can successfully copy texts and paste them somewhere else. I didn't
pay attention to the copy-and-paste problem because I usually use latex +
dvipdfmx work flow (using TeXLive2009 on a Mac), which can solve the problem
using cid-x.map mechanism.
Recently, one of my colleauge (using TeXLive 2011 on a MS-Window-PC) encounters
such problem using pdflatex work flow. It seems that only bsmi and bkai
(pre-installed in TeXLive distribution) have such capability. Other CJK fonts
don't.
I would like to make other CJK fonts to have the same capability, but I don't
know where to start.
The following is a minimal LaTeX code to have a successful PDF (using pdflatex).
------ begin >>>>>
\documentclass[12pt]{article}
\usepackage{cmap}
\usepackage[T1]{fontenc}
\usepackage{CJKutf8}
\begin{document}
\begin{CJK}{UTF8}{bsmi}
This is a test.
中文排版測試。
用的是 pdflatex。
\end{CJK}
\end{document}
<<<<< end ---------
If I attempt to use Type 1 fonts of cw family (available at
<ftp://cle.linux.org.tw/tex/cjk/fonts/cwt1/>), say 'cwkb', in the example
above, the resultant PDF looks fine but its copy-and-paste text has garbled
Chinese text. This is obviously a sympton that ToUnicode map is not set
properly for this font.
I notice that the file c70bsmi.fdx has some code to deal with ToUnicode stuff,
whereas cwkb does not even have c70cwkb.fdx. Is this the right place to work
with? creating a c70cwkb.fdx file with similar code in it?
Any suggestion and input is welcome. Thanks in advance.
