I got a bit further with it, but it is still not working as it  
should. I added a new method to BCSymbolSet,  
stringByRemovingUnknownCharsFromString that should filter a string  
and remove all characters that are not in the symbolSet. Because  
BCSymbolSet has a method containsSymbol, I need to convert each  
character in the string to a unsigned char, then get the symbol, and  
then do the test. That's all fine, and the guessing code now works as  
it should for the Peptides demo. However, for the Translation demo,  
it crashes at the line

     [result appendString: [NSString stringWithUTF8String: bytes]];

Anyone has an idea what I am doing wrong here?  Maybe I should add  
all the bytes together, and then convert it back to an NSString? Not  
sure how to do that, though.
