How to pass special character such as "&"

One of my fields is a URL which contains “&”. It changes that to a safe character \u0026.

How do I make it escape that in mockaroo?

Where are you seeing the encoding occurring for the “&” character in your URL? Are you creating a new Schema? Dataset import?

I am also wondering to how preserve the & character as part of a constructed URL.

I am just constructing a url as one of the fields in a schema e.g. https://somewebsite.com?p1=foo&p2=bar.
Instead, I get this: https://somewebsite.com?p1=foo\u0026p2=bar
