Java: convert UCS2 to UTF-8

While convert UCS2 into UTF-8, I hit UnsupportedEncodingException. So I use UTF-16 instead and it work well (at least till the time I write this post):

public String ucs2ToUTF8(byte[] ucs2Bytes) throws UnsupportedEncodingException{

    String unicode = new String(ucs2Bytes, "UTF-16");
   
    String utf8 = new String(unicode.getBytes("UTF-8"), "Cp1252");
   
    return utf8;
}
