What is Unicode in Java with example?

Unicode is a computing industry standard designed to consistently and uniquely encode characters used in written languages throughout the world. The Unicode standard uses hexadecimal to express a character. For example, the value 0x0041 represents the Latin character A.

What is Unicode with example?

The code point is a unique number for a character or some symbol such as an accent mark or ligature. Unicode supports more than a million code points, which are written with a “U” followed by a plus sign and the number in hex; for example, the word “Hello” is written U+0048 U+0065 U+006C U+006C U+006F (see hex chart).

Why do we use Unicode in Java?

Character encoding is the process for assigning a number for every character. The central objective of Unicode is to unify different language encoding schemes in order to avoid confusion among computer systems that uses limited encoding standards such as ASCII, EBCDIC etc.
