How do I remove  from the beginning of a file?

Question

I have a CSS file that looks fine when I open it using gedit, but when it\'s read by PHP (to merge all the CSS files into one), this CSS has the following characters prepend

Answer 1

BOM is just a sequence of characters ($EF $BB $BF for UTF-8), so just remove them using scripts or configure the editor so it's not added.

From Removing BOM from UTF-8:

#!/usr/bin/perl
@file=<>;
$file[0] =~ s/^\xEF\xBB\xBF//;
print(@file);

I am sure it translates to PHP easily.
