the DXF declared version, the acad version reading it *and* some

system variables to be put in the header handled only by newer acads

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

bigfonts which are a massive PITA). Common denominator solution:

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

Windows)

|
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

in no more details...
