@cindex BOM
@cindex Byte Order Mark
From @ref{Stream Encoding}, you may have got the impression text-files are
complicated. This section deals with a related topic, making live often
easier for the user, but providing another worry to the programmer.
@strong{BOM} or @emph{Byte Order Marker} is a technique for
identifying Unicode text-files as well as the encoding they use. Such
files start with the Unicode character @code{0xFEFF}, a non-breaking,
zero-width space character. This is a pretty unique sequence that is not
likely to be the start of a non-Unicode file and uniquely distinguishes
the various Unicode file formats. As it is a zero-width blank, it even
doesn't produce any output. This solves all problems, or ...

Some formats start of as US-ASCII and may contain some encoding mark to
switch to UTF-8, such as the @code{encoding="UTF-8"} in an XML header.
