   /VERTICAL
   /NOVERTICAL (default)

   Specifies vertical writing mode for Chinese, Korean, and
   Japanese multibyte characters. When /VERTICAL is specified,
   multibyte characters are rotated counterclockwise by 90 degrees
   and printed in lines from left to right; when the printed page
   is rotated 90 degrees clockwise, the characters can be read in
   vertical lines from right to left. In vertical mode, single-byte
   characters in languages such as English are still printed
   horizontally from left to right.
