为什么'？'在java中打印unicode字符时显示为输出 [英] why '?' appears as output while Printing unicode characters in java

问题描述

在java中打印某些unicode字符时，输出为？。为什么会这样，有没有办法打印这些字符？

While printing certain unicode characters in java we get output as '?'. Why is it so and is there any way to print these characters?

这是我的代码

String symbol1="\u200d";
        StringBuilder strg = new StringBuilder("unicodecharacter");
        strg.insert(5,symbol1);
        System.out.println("After insertion...");
        System.out.println(strg.toString());

输出为
插入后...
unico？decharacter

Output is After insertion... unico?decharacter
