<0xEF,0xBB,0xBF> character showing up in files. How to remove them?

You can easily remove them using vim, here are the steps:

1) In your terminal, open the file using vim:

vim file_name

2) Remove all BOM characters:

:set nobomb

3) Save the file:

:wq

Another method to remove those characters - using Vim:

vim -b fileName

Now those "hidden" characters are visible (<feff>) and can be removed.

Thanks for the previous answers, here's a sed(1) variant just in case:

sed '1s/^\xEF\xBB\xBF//'
