Java unicode where to find example N-byte unicode characters

Question

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.

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.
