Special characters in text

Question

How to remove special characters in a value for ex. "Radial™". Due to presence of "TM" in "Radial" facing issues. Is there a way to remove such characters from entire json file. The special text could be dynamic.

Answer 1

non-US-ASCII (ie outside 0x0-0x7F) characters

 public static void main(String[] args) {
        String s = "Radial™";
        s = s.replaceAll("[^\\x00-\\x7f]", "");
        System.out.println(s);
    }

Output

Radial

Answer 2

如果仅计划仅支持US-ASCII，则可以循环访问String的字符并删除所有值大于255的字符
