If you are familiar with LaTeX and interested in writing Bengali documents (or any other Indic documents) using it then you might find this post relevant.
In brief, LaTeX is a type-setting system which is widely used in scientific communities for preparing technical articles.
Here, instead, I will be interested in writing Bengali documents using LaTeX. The first Bengali typesetting system using LaTeX was the well known Bangtex package by Palash B. Pal. Bangtex does produce good quality documents.
However, main inconvenience in using Bangtex package is its input method. One needs to follow a specific transliteration scheme. This suffices if you want to create PS/PDF file at the end. However if you also want to create html pages for the same documents using latex2html then you are out of luck.
Now wouldn’t it be great if you could type your Bengali (or any other Indic) documents using standard Unicode in LaTeX as you would do with any other application?
Here comes the new revolution, XeTeX, a new type-setting system based on a merger of Donald Knuth’s TeX system with Unicode and modern font (OT/AAT) technologies. This means you no longer need to have special metafonts for your language to be present in the system. Instead you can use standard OTF/TTF fonts those are available in your system, for LaTeX as well.
No more talking… here goes the image of output PDF file.
Above document is created using the following latex source file
\documentclass{article}
\usepackage{fontspec}

% This file is a sample tex file to illustrate use of

\font\serif="FreeSerif:script=beng"
\font\serifbb="FreeSerif:script=beng" at 24pt
\font\deffont="FreeSerif:script=beng" at 14pt
\font\mukti="Mukti Narrow Bold:script=beng"

% "script=beng" in above lines ensures that appropriate
% complex text rendering engines are used for proper

আমাদের স্কুলের যত ছাত্র তাহার মধ্যে এমন কেহই ছিল না, যে পাগলা দাশুকে
না চিনে। যে লোক আর কাহাকেও জানে না, সেও সকলের আগে পাগলা দাশুকে চিনিয়া
লয়। সেবার একজন নূতন দারোয়ান আসিল, একেবারে আনকোরা পাড়াগেঁয়ে লোক, কিন্তু
প্রথম যখন সে পাগলা দাশুর নাম শুনিল, তখনই সে আন্দাজে ঠিক ধরিয়া লইল যে,
এই ব্যক্তিই পাগলা দাশু। কারণ তার মুখের চেহারায়, কথাবার্তায়, চলনে চালনে
বোঝা যাইত যে তাহার মাথায় একটু 'ছিট' আছে। তাহার চোখদুটি গোল-গোল,
কানদুটা অনাবশ্যক রকমের বড়, মাথায় এক বস্তা ঝাঁকড়া চুল। চেহারাটা দেখিলেই
মনে হয়---

XeTeX is available as standard component of TeXLive distribution. If you are using latest (K)ubuntu then you can
sudo apt-get install texlive-xetex
to install it. To test above sample tex file you can cut-n-paste to a file say sample.tex then compile it using
xelatex sample.tex
If everthying goes fine then you should get sample.pdf as your output document. In case you need to edit the latex source file, you can use any editor of your choice like kate, gedit or even vim. Of course, you can also use specialized LaTeX editor like kile (KDE Integrated LaTeX Environment) where you can view output document simply in one click!!
Update (Jul 8, 2010): If you are facing “double-quote” mixed-up problem that causes Latex compilation error while copy-pasting from the browser then please download the sample.tex file here.
