Easy detection of BOM

[mwhiting]

Hi Monks. I have a script on a webserver where I need to detect the presence or absence of a BOM from the start of a datafile. I have an existing subroutine that opens the file and reads the first record just to find out how many fields it has, and I will be adding it there.

What's an easy way of doing this? I am wondering if File::BOM is the way to go, and from cpan.org I see it has this function:

use File::BOM
open_bom(FH, $file)
$encoding = get_encoding_from_filehandle(FH)

I know some people say not to bother with checking, but in this case I need to know for the purposes of later code.

Thanks!

Sure, File::BOM is the way to go, why not :)

Kinda related are file/File::LibMagic, mimetype
