I have some NSData that may or may not contain invalid UTF-8, but any parts of it that are valid UTF-8 should be interpreted as such. If I use [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding], it just returns nil if the data has invalid UTF-8 anywhere. How can I get it to replace the invalid UTF-8 with �, like TextEncoder does?

You'd probably have to write your own "decoder". – matt Dec 23 '20 at 01:42
