Hey, I found something useful.
The problem in the round trip binary data ===> string ===> binary data is that in standard western character sets, there are a lot of slots which are marked "undefined". I had for instance a problem with 0x81 (decimal 129) which was transformed into 0x3f (question mark). I found out that the Arabic Character Set Cp1256 has all slots used, so can be used as a vehicle to do round trips with binary data using the filterchain framework.
