codepage conversion
i'm trying to build the odcopyex application with codepage conversion.
i changed the call to read the file to:
pdb = svcs.readfile(argv[1], true); // true == codepageconversion
this works perfectly for windows, but for hp-ux the codepage is cp_undefined and so the result is bad.
but if i manually change the default value in exsystemservices::exsystemservices() to cp_ansi_1252 or to cp_8859_1 it doesn't work either.
is this feature supported on unix?

do you mean you have overridden oddbsystemservices::systemcodepage() and it does not work?
on windows default implementation of this function returns current code page and on other platforms - undefined.

the problem is i have a dwg file which has as $dwgcodepage ansi_1251 (kyrillic) and want a dxf file with ansi_1252.
by using the windows build of the modified odcopyex the codepage is changed to ansi_1252 and the kyrillic characters are replaced with their correct unicode values (eg \u+0411).
by using the hp-ux build using following modification of exsystemservices.cpp the codepage is also changed to ansi_1252 (tried also cp_8859_1) but the kyrillic characters are replaced with wrong unicode values (eg \u+00fc).
before:
exsystemservices::exsystemservices()
: m_codepageid(cp_undefined)
{
#ifdef _win32
...
#endif
}
after:
exsystemservices::exsystemservices()
: m_codepageid(cp_ansi_1252) // or cp_8859_1
{
#ifdef _win32
...
#endif
}
codepage conversion works properly when odcodemapper class is initialize.
you have to do it once during start application.
for example:
#include "odcharmapper.h"
...
void main(...)
{
odcharmapper::initialize("c:\\adinit.dat");
...
}
file "adinit.dat" you can find in c dwg library (open dwg toolkit).

hello this doesn't work as expected on hp-ux.
attached you will find the changed sourcecode of odcopyex.cpp and a dwg file in ansi_1251.
if i convert the file to dxf using this modified odcopyex all cyrillic characters are converted to wrong unicode values.

your code is right. there is a problem with supporting big-endian byte ordering for odcharmapper class in dwgdirect. it will be fixed in next version.
thanks you for report.
