You're getting big endian unicode text. Coerce it to typeUTF8Text and things might be better for a console printout.

I am not sure how to do that, but isn't there an easy way to make this a proper NSString? The text is showing just fine when shown in an NSView, by the way, when using binding of the NSString variable.

Folks agree that you're not getting a valid input. If you have no options to change the input, then the easiest thing is to get the raw bytes and take a chance on something similar to CFStringCreateFromExternalRepresentation() or CFStringCreateWithFormat () since we've seen the bytes are big endian. CFStringCreateWithFormat () presumes a lot in terms of encoding while other raw byte constructors make you guess.

So (c99):

SInt32 size = AEGetDescDataSize( &desc );
UInt8 buffer[size + 2];
bzero( &buffer, size + 2 );
err = AEGetDescData( &desc, buffer, size );

NSString *nstr = (NSString *)CFStringCreateWithFormat ( kCFAllocatorDefault, NULL, CFSTR( "%S" ), buffer );

HTH,
