I have seen questions like this and this but I think my question is different because it is in an RTL environment and uses non-Roman script.
I have a url that appears mixed-script in the address bar of my Chrome browser. When I copy/paste the URL from the address bar of my browser it converts the non-ascii characters. And hyperref is happy.

But in my pdf I want to give the label of the URL the appearance of a mixed-script URL, just as it appears in the browser. So the label of the URL in hyperreff needs to contain both Roman and Arabic characters. I don't know how to get this to work. The commented-out lines in the script below tell roughly what I want, but when they are included it produces errors, understandably.
Here is my MWE:
\documentclass{article}
\usepackage{polyglossia}
\usepackage{hyperref}
\setmainlanguage{arabic}
\setotherlanguage{english}
\newfontfamily\arabicfont[Script=Arabic]{Scheherazade}
\let\arabicfonttt\ttfamily
