## This is sort of a hack. XML::Parser automatically makes everything
## UTF-8, and that is causing severe problems with the serialization
## of database records (what happens is this: we construct a string
## consisting of pack('N', length($string)) . $string. If the $string SV
## is flagged as UTF-8, the packed length is then upgraded to UTF-8,
## which turns characters with values greater than 128 into two bytes,
## like v194.129. And so on. This is obviously now what we want, because
## pack produces a series of bytes, not a string that should be mucked
## about with.)
##
## The following subroutine strips the UTF8 flag from a string, thus
## forcing it into a series of bytes. "pack 'C0'" is a magic way of
## forcing the following string to be packed as bytes, not as UTF8.
