Thanks for the answers. The following factors should be considerd when
dealing with unicode characters in python:
1. Declaring # -*- coding: utf-8 -*- at the top of script
2. Opening files with appropriate encoding:
txt = codecs.open (filename, 'w+', encoding='utf-8')

My program works fine now. There is no specific way of adding unicode
characters in list or dictionaies. The character itself has to be in
unicode.

Cheers,
