The proposal's problem statement doesn't make much sense. There is no 
escaping required (error and type checking code removed for simplicity):

NPObject* window = NULL;
NPN_GetValue(inst, NPNVDOMWindow, &window);

NPVariant documentv;
NPN_GetProperty(inst, window, NPN_GetStringIdentifier("document"), 

NPObject* document = NPVARIANT_TO_OBJECT(documentv);
NPVariant title;
STRINGZ_TO_NPVARIANT("mynewtitlestring", title);
NPN_SetProperty(inst, document, NPN_GetStringIdentifier("title"), &title);
