I guess I prefer an option bit. Howevever...

...if a utf-8 option is negotiated between origin
and target is it possible for me to subsequently
return a UKMARC (or other national format) record? 
MARC21 is not a problem as you can have unicode
MARC21 records, but UKMARC records "use an
extended ASCII (8 bit) character set". There
is no MARC leader byte in UKMARC to indicate
an alternative unicode/utf-8 encoding.

Would a request for a particular record syntax
override any utf-8 option bit set at Init time?
