How to handle special characters in the password of a Postgresql URL connection string?

Using a Postgresql URL connection string in the format of:

postgresql://user:secret@localhost

How do I handle special characters in that string (e.g., $) so that it will actually function when I connect to my postgres database?

I've tried simply URL encoding it, so for example, "test$" becomes "test%24" ... but that seems to be a problem as I get a "FATAL: password authentication failed " error when attempting to use it.
