如何替换java字符串中的unicode字符

How can I replace a unicode character in java string

提问by user3173814

I have an issue in my project that is replacing a unicode charcter with another unicode character in a Java string. After searching and trying different codes , I did'nt get the solution for that I want to replace a character in Persian to another character in Persian with different unicode number. I really appreciate any help.

我的项目中有一个问题，就是用 Java 字符串中的另一个 unicode 字符替换 unicode 字符。在搜索并尝试不同的代码后，我没有得到解决方案，因为我想将波斯语中的一个字符替换为具有不同 unicode 编号的波斯语中的另一个字符。我真的很感激任何帮助。

thanks

谢谢
