There is *no* black... the white does it on paper, usually, and

anyway it depends on the plotter configuration, since DXF colors

are meant to be logical only (they represent *both* line color and

width); later version with plot styles only complicate the matter!

Also before R15 unicode simply is not supported (you need to use

use Latin1 (and however someone could choke on it, anyway). Sorry

to 255 bytes records (it was later raised to 2048); since I'm lazy

and text so long is not probable I just don't implement this rule.
|
|
If someone is interested in fixing this, you have to emit the first
|
|
partial lines with group code 3 (max 250 bytes each) and then finish
|
|
with a group code 1 (less than 250 bytes). The DXF refs explains it
