The appearance stream is that gibberish. If you know all sizes in 
advance then one solution is to reactivate the setNeedAppearances(true) 
and not to set any appearance streams (that's the gibberish), e.g. use a 
COSDictionary instead of a COSStream (but it must be different object 
for on and off).  The open with Adobe Reader. Then save that one. Then 
open it with PDFDebugger and go to the appearance streams. Copy that one 
over the gibberish.

If you don't know the sizes then setNeedAppearances(true) and keep it 
that way. This will work with Adobe Reader but possibly not with other 
readers.

Sorry, I don't understand you there.
