Good news: I asked on the Irrlicht board, and their very helpfull answer
was, use some obsucre conversation function:
void
setWindowCaption(SV* classname, char* caption)
PREINIT:
wchar_t mytitle[512];
CODE:
// TODO: find out length of scalar and alloc memory for myTitle?
mbstowcs(mytitle, caption, 512);
device->setWindowCaption(mytitle);
This works! :) However, whoever thought up the name of these conversion
functions should be shot. Honestly, who can remember these cryptic garbage
names like mbscwsomethingfoobar? Glad that I have to write it only once as
macro in XS :)
Best wishes,
Tels
