This should be a useful performance improvement. I've got some 100MB files and they take quite a few seconds to read through from my local SSD - and imagine if someone was reading across the network.
If the unicode byte-order mark is read in the first line of the file, it really makes no sense to read the rest of the file off disk.
I fixed the unit tests in the previous PR because I wanted to assure myself this introduced no regression (it appears not to.)
cheers
