Actually, I don't necessarily see anything wrong with the lack of BOM
in this case: these are Windows-internal log files, meant to be read
by utilities who know the encoding, not by general-purpose text
editors.  UTF-16 is the native encoding used by Windows low-level APIs
and the kernel for non-ASCII text, so seeing that in a temporary file
shouldn't be a surprise.  And of course, Windows doesn't need a BOM
because it uses only one endianness.

A BOM in UTF-8 is another matter, of course...
