Z39.2 counts octets, but say they're counting characters. If you find a
record that appears to use characters instead of bytes, ignore it; it's
legacy R'LMARC, which has been declared officially dead- it's Z39.2/ISO2709
that are eternally lying.
UNIMARC *can* allow UCS-2 encodings in data fields, but it does not seem
possible for this to imply that lengths are in characters on any charitable
reading. This is because the information that UCS-2 will be used is located
at a non-zero offset within a fixed field. If offsets were in character
units, rather than bytes, it would not be possible to locate this value
within the field.
