Could anybody let me know what is the problem?
The Unicode character "\uFEFF" is the "byte-order mark". This is commonly used in Windows systems, not so commonly on others, which tend to get confused by it. You didn't say what system you are working on and what encoding was used for the file; those are likely both important.
