public void eval() {
        // get the value and replace with
        String stringValue = org.apache.drill.exec.expr.fn.impl.StringFunctionHelpers.toStringFromUTF8(input.start,
input.end, input.buffer);
        String fromEncodeValue = org.apache.drill.exec.expr.fn.impl.StringFunctionHelpers.getStringFromVarCharHolder(fromEncode);
        String toEncodeValue = org.apache.drill.exec.expr.fn.impl.StringFunctionHelpers.getStringFromVarCharHolder(toEncode);

        try {
            String toEncodeStringValue = new String(stringValue.getBytes(fromEncodeValue),toEncodeValue);
            out.buffer = buffer;
            out.start = 0;
            out.end = toEncodeStringValue.getBytes().length;
            buffer.setBytes(0, toEncodeStringValue.getBytes());
        } catch (UnsupportedEncodingException e) {
