try {
    // Convert from Unicode to UTF-8
    String string = "\u003c";
    byte[] utf8 = string.getBytes("UTF-8");

    // Convert from UTF-8 to Unicode
    string = new String(utf8, "UTF-8");
} catch (UnsupportedEncodingException e) {
}

You can try converting the string into a byte array

您可以尝试将字符串转换为字节数组

byte[] utfString = str.getBytes("UTF-8") ;

and convert that back to a string object by specifying the UTF-8 encoding like

并通过指定UTF-8编码将其转换回字符串对象

str = new String(utfString,"UTF-8") ;
