为什么这段代码总是产生'？'的输出 [英] Why this code always produce output as '?'

问题描述

我们知道java遵循unicode系统，它支持多种语言的所有字母表。我搜索并发现अ的Unicode值是2309，आ的值是2310，这是DEVANAGRI语言的字母表。我写的代码是这样的。

As we know java follows unicode system which supports all alphabets of many languages. I searched and found that Unicode value for अ is 2309 and value for आ is 2310 which are alphabets of DEVANAGRI language. The code i have written is something like this.

class Test
{
    public static void main(String args[])
    {
        char a=(char)2310;
        System.out.println(a);
    }
}

无论我写2309或2310输出是' ？'总是。如何发生这种情况？

No matters I write 2309 or 2310 the output is '?' always. How this is happening?
