I don't use Safari/iOS, so I don't know for certain, but AFAIK the answer is no. However, I believe in the most recent version of iOS Safari there will be an option in the left-hand corner of the URL to adjust text size for any page you're on, and Safari will remember that setting on a per-domain basis. But again, I don't own an iOS device, so I'm not sure exactly what algorithm it uses to resize. It says it's text resizing, but maybe behind the scenes it's doing something different.
