So on the server side, I got a InputStream object, and I try to wrap it as an InputStreamReader with &#8220;UTF8&#8221; as the charset. But I notice when I upload a file encoded in US-ASCII can also work. It seems Java can automatically transform the file from all other charset to UTF8. Am I am right. Can anyone explain me how the charset attribute works.
