[poppler] question / possible bounty - XFA support

Tue Sep 5 12:51:22 UTC 2017

William,

if I may have another question (although I'm probably out of 
scope of this ML, if so, I'll ost it into gs maillist)
- conversion seems to work fine, but resulting PDF does not
display accented characters properly.. it seems that source data
are in cp1250 encoding, but resulting file uses different encoding
and characters are mangled..

I was playing with -sDSCEncoding but it's not documented much
and does not seem to have any effect..

did somebody deal with similar problem?

any answer would be greatly appreciated

thanks a lot in advance

BR
