The 128 most commonly used characters are contained in Table 0, these are the standard upper and lower-case letters
of the Roman alphabet, numerals, punctuation and the more common accented characters. In normal text transmission,
Table 0 is used most of the time. Table 1 contains other accented characters. Miscellaneous characters, mathematical
symbols, the line drawing character set and accents without associated symbols are contained in Table 2.
Table 3 contains the block mosaics for the basic alpha-mosaic service and also the new smooth mosaics.
The four tables stored in the external RAM (Tables 4 to 7) are used for DRCS.
