    EmojiconEditText edMessage = (EmojiconEditText) findViewById(R.id.edtMessage);
 @Override
    public void onEmojiconBackspaceClicked(View view) {
        EmojiconsFragment.backspace(edMessage);
    }

    @Override

        EmojiconsFragment.input(edMessage, emojicon);
    }

}

Please help me to fix the issue.

By using edMessage.getText().toString().trim() you can get string

Converting String to Unicode

    public static String unicodeEscaped(char ch) {
            if (ch < 0x10) {
                return "\\u000" + Integer.toHexString(ch);
            } else if (ch < 0x100) {
                return "\\u00" + Integer.toHexString(ch);
            } else if (ch < 0x1000) {
                return "\\u0" + Integer.toHexString(ch);
            }
            return "\\u" + Integer.toHexString(ch);
        }

        String unicode = "";
       String text = _msgEditText.getText().toString().trim();
       for (int i = 0; i < text.length(); i++) {
       unicode = unicode+Constant.unicodeEscaped(text.charAt(i));
                            }
text = unicode;

And for decoding it you can use common-lang.jar file.

_msgString = StringEscapeUtils.unescapeJava(_msgString); // for decoding unicode to string or for similar language
