Buoa, I can imagine ;) but unfortunately it's not the way I can go 
because my resulting PDF will be somewhat around 500-800MByte in size.
In addition I'll have about 14 different language kinds for each of them :/

Therefore I need another solution, at last I'll use the hexeditor but 
currently I've still hope that someone knows how to use it ;)


Thanks
