I'm using this code to convert to an NSString.
NSString *info =[[NSString alloc] initWithBytes:data length:sizeof(data) encoding:NSUnicodeStringEncoding];
But I'm just getting foreign characters and wing-dings in the output.
What am I doing wrong?
I'm only interested in the first 3 sections separated by '\xa7'.

Answer 1

Looks like I should've used
NSString *info =[[NSString alloc] initWithBytes:data length:sizeof(data) encoding:NSUTF16LittleEndianStringEncoding];
