What's the equivalent of URLencode for Redshift?

Using Redshift, I need to encode a string before I pass it as a GET string in a URL. Is there an equivalent of URLencode() for Redshift SQL? I am passing data from Redshift to an email marketing program, that will then use the data to form a custom link. I am already doing a number of things to prep the data for the email marketing program as part of my SELECT statement and it would be cleanest if I could prep one field with URLencode() as part of the other data prep.
