是否可以在Java中动态生成Unicode字符？(Is it possible to dynamically generate Unicode characters in Java? [duplicate])

 Java：如何从字符串“\ u00C3”等 5个答案 创建unicode 
 
 
 
 
 基本上，我想在System.out.println行中使用Unicode符号，但这些Unicode字符需要动态生成。 
 
 例如，取符号U+2074 ， U+2075和U+2076 ，它们分别返回x^4 ， x^5和x^6 。 要用Java打印它我会使用\u2074 ， \u2075和\u2076 ，但如果我想根据另一个值生成它们（即\u207x ，其中x是变量）怎么办？ 
 
 如果我使用PHP，我会使用变量变量 ，这将非常方便。 
 
 我甚至考虑使用hack如将u207保存为String，对x的值进行计算并将此值附加到字符串，但是在字符串中引入\符号时会出现问题： 
 
String unicodeBase = "u207";
// I do something to get a value for x
String unicodeChar = "u207" + x;
System.out.println("\unicodeChar");
 
 如果我这样做，我得到一个illegal unicode escape错误，这是预期的。 但是，如果我转义\符号，那么输出是一个未处理的字符串： 
 
System.out.println("\\unicodeChar");
 
 这将返回字符串unicodeChar 。 
 
 那么，是否可以在Java中动态生成Unicode字符？

Basically, I would like to use Unicode symbols in my System.out.println lines, but these Unicode characters would need to be dynamically generated.
 
For example, take symbols U+2074, U+2075 and U+2076, which return, respectively, x^4, x^5 and x^6. To print them in Java I would use \u2074, \u2075 and \u2076, but what if I want to generate them based on another value (i.e. \u207x where x is a variable)?
 
If I were using PHP, i would use variable variables for this which would be extremely handy.
 
I even went as far as thinking about using a hack like saving u207 as a String, making my calculations on the value of x and appending this value to the string, but then there are issues introducing the \ symbol inside a string:
 
String unicodeBase = "u207";
// I do something to get a value for x
String unicodeChar = "u207" + x;
System.out.println("\unicodeChar");
 
If i do this, I get an illegal unicode escape error, which is expected. But then, if I escape the \ symbol, then the output is a string that is not processed:
 
System.out.println("\\unicodeChar");
 
This returns the string unicodeChar.
 
So, is it possible to dynamically generate Unicode characters in Java?
