2.13.4.6. Character Individual Double Width
The bit DW (double width) marks the left half of a char-
acter with double width.
The character to its right will be overwritten by the right
half.
If the DW bit of the following character (here the ‘X’) is
also set to ‘1’; the right half of the ‘A’ is overwritten by
the left half of the ‘X’.
If a character is displayed in double width mode the
attribute settings of the left character position are used
to display the whole character.
