docs: Set the name of the character set used for the row delimiter. This is
  also used by subclasses to interpret field delimiters, comment strings,
  and for configuring {@link FieldParser}s.
  
  These fields are interpreted when set. Changing the charset thereafter
  may cause unexpected results.
