!pdfTeX error: pdflatex (file ../latex/lthuni.enc): cannot open encoding file f or reading

[iPAS]

Using 'thailatex package version 0.4.6-3' of Ubuntu 12.04.1 LTS (Release:12.04),
I got an error when trying to build a PDF document from a Tex file.

> pdflatex test.tex

test.tex:
\documentclass{article}
\usepackage[thai]{babel}
\usepackage[utf8x]{inputenc}
\title{ทดสอบภาษาไทย}
\author{นาย Dubber}
\begin{document}
\maketitle
\section{สวัสดีชาวโลก}
อืม ใช้ได้ ไม่มีปัญหา
\end{document}

The error shown as following:
...
!pdfTeX error: pdflatex (file ../latex/lthuni.enc): cannot open encoding file f
or reading
 ==> Fatal error occurred, no output PDF file produced!

After I track this problem for while, found that three mapping files of 'thailatex' package,
in /usr/share/texmf/fonts/map/dvips/tlwg,
were wrong refer to the 'lthuni.enc' file.

To solve the problem, just revise those files.
Let they point to new destination of 'lthuni.enc', /usr/share/texmf/fonts/enc/dvips/thai/lthuni.enc.
Then, command
> sudo updmap-sys
That's all.

ps. the revised *.map were attached.

The bug should belong to latex-fonts-thai-tlwg.

And I don't think putting absolute path in the map file is neccessary. 'kpathsea' can do the file search for you, given that the target file is properly installed in one of its search paths.

I guess latex-fonts-thai-tlwg in 12.04 is 1:0.4.17-1ubuntu1, right? Let's check if the Ubuntu-specific patch has done the job correctly. (I am the Debian maintainer, not Ubuntu. That's all I can comment.)
