Indian Languages in Latex

Myself and Prof.Partha were looking for generating PDF files with Tamil and English content using Latex.

Found that.
We can generate multi lingual pdf files using latex easily.
We need to supporting fonts installed anyhow.

Here is the sample code for this.

 

\documentclass{article}
%Always start xelatex files with these in preamble. This helps in defining the script and fonts
\usepackage{fontspec}
%Set the main languge next as main font.
\setmainfont[Script=Devanagari]{Lohit Hindi}

%Set rest of the languages l;ike this. Experiment a bit. script=punjabi did not work. Replaced with gurmukhi and it works.

\newfontfamily{\tam}[Script=Tamil]{Akshar Unicode}
\newfontfamily{\tel}[Script=Telugu]{Akshar Unicode}
\newfontfamily{\kan}[Script=Kannada]{Mallige}
\newfontfamily{\Guja}[Script=Gujarati]{Lohit Gujarati}
\newfontfamily{\ben}[Script=Bengali]{Lohit Bengali}
\newfontfamily{\Punj}[Script=Gurmukhi]{Lohit Punjabi}

%English does not need any script specifiction! Just define the font.
\newfontfamily{\eng}{Arial}
\begin{document}
%No need to define script as this is the manin font set. Like defalut.
नमो पकवते नारायणाय! \\
%Switch language like this. { begins the changed line. \xxx denotes the switched  language. Use the same definition as denoted in preamble. } will end the switch and default to main unless again specified.
{\tel నమో పకవతే నారాయణాయ!}\\
{\kan ನಮೋ ಪಕವತೇ ನಾರಾಯಣಾಯ
}\\
{\Guja નમો પકવતે નારાયણાય!}\\
{\Punj ਨਮੋ ਪਕਵਤੇ ਨਾਰਾਯਣਾਯ!}\\
{\ben নমো পকবতে নারায়ণায়!}\\
{\tam நமோ பகவதே நாராயணாய!}\\

{\eng namo bhagavate naraayanaaya}\\
%the next line does not begin liekt he ones above. so it defaults to mainfont which is devanagari.
शुभम।
\end{document}

 

Check the output too.

Thanks for Dr.Vasudevan Tirumurti for the latex file.
