Answer 3

From the syntax itself, it should be clear that that line is encoding some characters that couldn't be found in ASCII. Basically, it's the taking char and converting/encoding to unicode.
Why do we need encoding?
character encoding provides a key to unlock (ie. crack) the code. It is a set of mappings between the bytes in the computer and the characters in the character set. Without the key, the data looks like garbage(like in your case a question mark?)

Answer 4

I'm not sure maybe Microsoft .net works differently.
Well, you can research that yourself and have fun. :)

Answer 5

So Console. OutputEncoding=Encoding.Unicode is an inbuilt method in java strings
