In BIFF5-BIFF8, the boldness and underline flags are still set in the options field, but not used on reading the font. Font
weight and underline type are specified in separate fields instead. The character set specifies the encoding used by cell
records that contain byte strings, for instance LABEL (➜5.63), RSTRING (➜5.89), FORMULA (➜5.50), or STRING
(➜5.102).
