[DotGNU]how to find ByteOrder Marks

[minddog]

I don't know how to find these marks from a streamFragment since I am unsure 
if there is a class that already does this.  Anyone help me out here? =)

        // TODO: find byte order mark 
// // EF BB BF = utf8
// // FE FF = utf16/ucs-2 little endian
// // FF FE = utf16/ucs-2, big endian
// // FF FE 00 00 = UTF-32/ucs-4, little endian
// // 00 00 FE FF = UTC-32/UCS-4, big endian
        // else ...
// encoding = System.Text.UT8Encoding(true);
