n.b. Any UTF file (other than UTF-8, which doesn't need it) should start with a BOM U+FEFF encoded the same as any other code point in the same file. RFC 2781 recommends that, if the BOM is missing, big-endian should be assumed. But...
A lot of software assumes little-endian, because for a while Windows programmers had not seen anything else. Sigh.
