CHARACTER SETS
The WST specification allows the selection of national character sets via the page header transmission bits, C12 to C14.
The basic 96 character sets differ only in 13 national option characters as indicated in Tables 17, 18, 19 and 20 with
reference to their table position in the basic character matrix illustrated in Table 16. The SAA5254 automatically decodes
transmission bits C12 to C14. Tables 12, 13, 14 and 15 illustrates the character matrixes.
