In java why a unicode character is checked by compiler even if it is enclosed inside comment?
That's interesting. Can you give an example of how Unicode is used in Java?
Sure. For example, if you wanted to print the Japanese word for "hello" in your Java program, you would need to use a Unicode escape sequence like this: "\u3053\u3093\u306B\u3061\u306F". This sequence represents the Unicode code points for each of the kanji characters in the word "hello".
