Java unicode where to find example N-byte unicode characters

I'm looking for sample 1-byte, 2-byte, 3-byte, 4-byte, 5-byte, and 6-byte unicode characters. Any links to some sort of reference of all the different unicode characters out there and how big they are (byte-wise) would be greatly appreciated. I'm hoping this reference also has code points like \uXXXXX.

How do I find Unicode for a character?

To insert a Unicode character, type the character code, press ALT, and then press X. For example, to type a dollar symbol ($), type 0024, press ALT, and then press X.

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 an example of a Unicode character?

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).

How many bytes is a character in Unicode?

Unicode uses two encoding forms: 8-bit and 16-bit, based on the data type of the data that is being that is being encoded. The default encoding form is 16-bit, where each character is 16 bits (2 bytes) wide.

There is no such thing as "1-byte, 2-byte, 3-byte, 4-byte, 5-byte, and 6-byte unicode characters".

You probably talk about UTF-8 representations of Unicode characters. Similarly, strings in Java are internally represented in UTF-16, so that Java char type represents a 16-bit code unit of UTF-16, and each Unicode character can be represented by either one or two these code units, and each code unit can be represented as \uxxxx in string literals (note that there are only 4 hex digits in these sequences, since code units are 16-bit long).

So, if you need a reference of Unicode characters with their UTF-8 and UTF-16 representations, you can take a look at the table at fileformat.info.
