java - 将字符串转换为其 Unicode 代码点

Question

假设我有一个字符串 foo = "This is an apple"

等效的 Unicode 代码点将是

"\\x74\\x68\\x69\\x73.........\\x61\\x70\\x70\\x6c\\x65 "

   T    h    i   s  ............. a    p    p    l   e

如何从字符串 foo 转换

到

字符串“\\x74\\x68\\x69\\x73.........\\x61\\x70\\x70\\x6c\\x65”

试试这个..

        public static String generateUnicode(String input) {
            StringBuilder b = new StringBuilder(input.length());
            for (char c : input.toCharArray()) {

                b.append(String.format("\\u%04x", (int) c));

            }
            return b.toString();
        }
