ENWW Printer-Specific Differences 2-101
The new algorithm for deciding whether or not to counter-rotate
characters (when using the Character Text Path Direction command’s
vertical-rotated printing mode) is as follows:
if (the current font contains a VE segment)
{
if(the character code* is NOT contained in
a VE range)
rotate
else
don't rotate
}
else
use the old logic
* The original character code, even if a galley character were
substituted at some point.
