While sending such kind of special characters to server you need to encode such input with the help of URLEncoder.encode(your_input, "utf-8") and while receiving such kind of data first of all you need to decode it with the help of URLDecoder.decode(your_data, "utf-8")

While sending such kind of special characters to server you need to encode such input with the help of **URLEncoder.encode(your_input, "utf-8")** and while receiving such kind of data first of all you need to decode it with the help of **URLDecoder.decode(your_data, "utf-8")**
I have also faced such kind of problem, so I followed encoding and decoding and resolved the problem. I think this will help you too.
