    """Parses a Unicode continuation field.
  
    These are of the form '<Name, First>' or '<Name, Last>'.
    Instead of giving an explicit range in a single table entry,
    some Unicode tables use two entries, one for the first
    code value in the range and one for the last.
    The first entry's description is '<Name, First>' instead of 'Name'
    and the second is '<Name, Last>'.

      pair: name and ('First', 'Last', or None)
