/* There are two issue in emitting the text:
|
|
- Our overline character (~) must be converted to the appropriate
|
|
control sequence %%O or %%o
|
|
- Text encoding in DXF is more or less unspecified since depends on
|
|
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
|
|
for the extended latin people. If somewant want to try fixing this
|
|
recent version seems to use UTF-8 (and not UCS2 like the rest of
|
|
Windows)
|
|
|
|
XXX Actually there is a *third* issue: older DXF formats are limited
|
|
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...
