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 the Tables 16, 17 and 18 with
reference to their table position in the basic character matrix illustrated in Table 15. The IVT1.1BMCX automatically
decodes transmission bits C12 to C14. Tables 12, 13 and 14 illustrate the character matrixes.
Character bytes are listed as transmitted from b1 to b7.
