Comment 4 for bug 99090

Well, I'm not too familiar with UTF-16 and I could be totally wrong, but its worth a try.
When you saved the file, the file was saved with the UTF-16 encoding (I guess this is the standard encoding for India, as you want to be able to use your Indian alphabetical characters).
It is possible (its just a wild guess) that apt-get will not recognise this encoding and get confused.
Can you try saving the file with an UTF-8 or western (ISO-8859-15) encoding? You will find the option at the botton of the dialog when you click the "Save as ..." entry from the File menu.
I would also delete the extra chinese/japanese characters at the end of the file.
