Convert UTF-16 unicode characters to UTF-8 in java

Question

When I got JSON then there are \\u003c and \\u003e instead of < and >. I want to convert them back to utf-8 in java. any help will be highly appreciated. Thanks.

Answer 1

You can try converting the string into a byte array

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

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

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

Answer 2

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) {
}
