WebJava supports Unicode character set so, it takes 2 bytes of memory to store char data type. To store char data type Java uses the Unicode character set. Unicode is a hexadecimal int type number. So in a Unicode number allowed characters are 0-9, A-F. It has a special format that starts with \u and end with four characters. Example:- \uxxxx
Java supports a wide array of encodings and their conversions to each other. The class Charset defines a set of standard encodingswhich every implementation of Java platform is mandated to support.

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 of Unicode, range …
WebJSONKit虽然很强大，但是一些特殊的Unicode，比如u0000是无法解析的。在github上作者解释了这个问题，说这个是内容提供的错误，不符合标准的内容，所以他不认为这个是自己的错误，这个是内容提供者的问题。作者的原话如下：Inthisparticularcase,theseservicesareveryclearly WebJava定义了两种类型的流，字节和字符。 System.out.println ()不能显示Unicode字符的主要原因是System.out.println ()是一个字节流，它只处理16位字符的低位8位。 为了处理Unicode字符 (16位Unicode字符)，您必须使用基于字符的流，即PrintWriter。 PrintWriter支持print ( )和println ( )方法。 因此，您可以像在System.out中使用它们一样使用这些方法 …
