Escaping the "%" character when used with URLEncoder/URLDecoder

I want to ask how could I escape the "%" character when using URLEncoder.encode(String, ENCODING)?

I have a String object that I want to send to the server side. This String object can contain the characters:
" ' / > < \ % ?
I encode the String in the client side using the "URLEncoder.ecode(String, "UTF-8")" method, but when I try to decode on the server side using "URLDecoder.decode(String, "UTF-8")" method, I get an IllegalArgumentException:

java.lang.IllegalArgumentException: URLDecoder: Incomplete trailing escape (%) pattern

So, my question is how can I encode my String object so that the "%" character (or any of the other characters) will be escaped and won't be considered as special character/s?

Thanks in advance!
