How to save '&' symbol in couchbase

I have url like,
https://drive.google.com/uc?export=download&id=FILE_ID

When I am trying to save the above url internally it is converting like,
https://drive.google.com/uc?export=download\u0026id=FILE_ID

Internally it is replacing ‘&’ to ‘\u0026’
But I want to store exact url which contain ‘&’.
