String "\u1110" getting converted to "?"

Question

When I am trying something below code:

String x = "\u1110";
System.out.println("value of x ="+x);

output :

value of x =?

1. Why output is coming like this ?
2. I would like to get the output same as \u1110 ?
3. How it is representing in String pool whether \u1110 or ?.

Answer 1

The String (and String pool) contains "ᄐ" (Unicode Character 'HANGUL CHOSEONG THIEUTH' (U+1110)). But, to answer your first question, your console doesn't (apparently) have a glyph for that.
