The MARC preview of staged records fails when a staged record contains
items with UTF-8 characters (see attached screenshots). That's because
in EmbedItemsInImportBiblio() the call to MARC::Record->new_from_xml()
does not specify 'UTF-8' as the optional encoding to use.

In intranet-error.log you'll get messages such as:
showmarc.pl: XSLT_Handler: :63: parser error : PCDATA invalid Char value 27
showmarc.pl:     <subfield code="o">889.3 \x1b(SVAU\x1bs</subfield>

I suggest we fix this by explicitly specifying 'UTF-8' as the encoding
to use whenever a call to new_from_xml() is made across the codebase.

For consistency, I also propose to standardise on the encoding name in
direct calls to new_from_xml(), and use 'UTF-8' from now on instead of
'utf8' or 'utf-8'.
