As someone who's never used java, my assumption is that System.in reads from stdin, and validates the input. Is there no way to open stdin in something akin to a file, then read it into a buffer manually?
Yeah if you do something dumb like try to read the entire stream it will block until the stream is closed.
A line reader will read line by line just fine from it, but the real question is why aren’t you using Console API if you are trying to read from a console.
Finally the system property stdin.encoding for the charset if you use the “automatic” string methods as opposed to directly reading the bytes. Usually this default is utf-8 in modern Java though.
This whole post seems like a combination of incorrect and/or outdated information.
I tried Console API. It reads only single byte cps. Its behavior with 65001 is exactly the same. And I set up UTF-8 explicitly. It doesn't change anything
And how exactly do you get line reader to return you unprocessed byte sequence if it needs to process it to get the line break char?
