OK, another quick questions.  It looks like my IO was
the problem.  LibXML knew it was UTF-8 (at least
$source_xml-> encoding said so) but this character came
in as UTF-8 and out as Latin-1 here:

  print $fh $source_xml-> toString();

When I used LibXML's toFH: 

  my $rc = $source_xml-> toFH($fh);

that got it right (or maybe I got lucky).  I opened
the file handle with:

  my $fh = new FileHandle "> $xmlFile";

Do I really need to specify the UTF-8 encoding for
each file handle something like this?

  my $fh = new FileHandle "> :encoding(utf-8)
$xmlFile";

Can I trust that toFH() will do the right thing?  What
about XML::LibXML's toFile()?  I don't see much about
this in the perldoc.

Thanks again,
Josh
