because a Unicode character might be encoded as more than one Char object. In particular, a string may contain multi-character units of text that are formed by a base character followed by one or more combining characters or by surrogate pairs. To work with Unicode characters instead of Char ...
Early Java versions represented Unicode characters using the 16-bit char data type. This design made sense at the time, because all Unicode characters had values less than 65,535 (0xFFFF) and could be represented in 16 bits. Later, however, Unicode increased the maximum value to 1,114,111 ...

A Unicode character, when encoded as UTF-16, takes “almost always” (not always) 16 bits: that’s because there are more than 64K unicode characters. Hence, a Java char is NOT a Unicode character (though “almost always” is). “Almost always”, above, means the 64K first code points...

In the Java programming language char values represent Unicode characters. Unicode is a 16-bit character encoding that supports the world's major languages. You can learn more about the Unicode standard at the Unicode Consortium Web site . Few text editors currently support Unicode text entry. ...
Description Inside annotations, non-ascii characters are escaped, even though outputEncoding is set to utf-8. Note that comments are displayed correctly in unescaped form. Like this: Reason This is because the codemodel library is being ...
The Unicode standard was initially designed using 16 bits to encode characters because the primary machines were 16-bit PCs. When the specification for the Java language was created, the Unicode standard was accepted and the char primitive was defined as a 16-bit data type, with characters in ...
Unicode was invented to represent and manipulate all the different characters not included in the traditional 7-bit ASCII encoding. Unicode assigns to each character a unique so called "code point". For example the letter "a" has as code point U+0061, while "Я"'s code point is U+042F...
