// `img` now contains a QR Code with an invalid vCard (with escaped content inside: %20, %0A and so on…)

Report this issue in Jira. The URL is fine (it must be escaped -- that's part of it being a URL). Type that URL in your browser, and you'll see a valid QR code that you can scan. But somewhere after you pass it to the image view, Titanium is corrupting it.

Use this code for your reproduction:

var win = Ti.UI.createWindow({
    backgroundColor: '#fff'
});
win.add(Ti.UI.createImageView({
    image: 'http://chart.apis.google.com/chart?cht=qr&chs=300x300&chl=BEGIN:VCARD%0AVERSION:2.1%0AN:Ipsum;Lorem;;;%0AFN:Lorem%20Ipsum%0AORG:Company%20Ipsum%0ATITLE:Lorem%20Ipsum%20developer%0ATEL:555%20555%20555%0AEMAIL:[email protected]%0AEND:VCARD&chld=H|0',
    width: 300, height: 300
}));
win.open();
