How to write Unicode text using LaTeX

Here is a ppt I made with my lab-mate Praveen Krishnan, where I have compiled how to write in LaTeX documents using different languages. I have compiled it from various sources ... I hope it is useful to you all...

file.tex:0:Emergency Stop

This latex error is a simple one but can make you go crazy. It does not give you much clue about where exactly the error occurs and the cursor goes to the beginning of the file. Well, the culprit lies in the end of the file. It is when we miss to end the document by mistake.
So just add \end{document} in the last line of the file and the error vanishes!
