How do I include special characters like @ and & in the cURL POST data? I'm trying to pass a name and password like:
curl -d name=john passwd=@31&3*J https://www.mysite.com This would cause problems as @ is used for loading files and & for specifying more than one key/value. Is there some way I can escape these characters? \@ and \& don't seem to work.

A special character is one that is not considered a number or letter. Symbols, accent marks, and punctuation marks are considered special characters. Similarly, ASCII control characters and formatting characters like paragraph marks are also special characters.
What is an &? & is called an ampersand symbol (pronounced “AM- per-sand”). Essentially, it means “and”. It is used both (a) in the body of the paper as part of a citation and (b) at the end of the paper as part of a reference.
cURL > 7.18.0 has an option --data-urlencode which solves this problem. Using this, I can simply send a POST request as
curl -d name=john --data-urlencode passwd=@31&3*J https://www.example.com Summarizing the comments, in case of mixed "good" and "bad" data and exclamation marks inside we can use on Windows:
curl -d "grant_type=client_credentials&client_id=super-client&acr_values=tenant:TNT123" --data-urlencode "client_secret=XxYyZ21D8E&%fhB6kq^mXQDovSZ%Q*!ipINme" https://login.example.com/connect/token How about using the entity codes...
@ = %40
& = %26
So, you would have:
curl -d 'name=john&passwd=%4031%263*J' https://www.mysite.com
