Yes the problem was related with BOM.
Used this function to remove the BOM chars of a UTF-8 file:
sub parse($) {
my $mydoc = shift ;
# check BOM
my $top1 = unpack("C", substr($mydoc, 0, 1));
my $top2 = unpack("C", substr($mydoc, 1, 1));
my $top3 = unpack("C", substr($mydoc, 2, 1));
# UTF-8
if($top1 eq 239 && $top2 eq 187 && $top3 eq 191) {
$mydoc = substr($mydoc, 3, length($mydoc) - 3);
}
return $mydoc;
}
and the idea was from the following code and its parse function:

Jalal,
Kindly reply via the mailing list so others can see the discussion.
That way others can benefit and/or help.
BOM is the Byte Order Mark used in Unicode to indicate an
important detail about the Unicode data stream.
Perhaps the Perl people can describe how to inhibit the BOM?
