// page will be used as a suggestion, and (if accepted by the user) the shortcut
// name will look really weird. For example, MacOS will convert a colon (:) to a
// forward-slash (/), and Windows will convert the colons to spaces. MacOS even
// goes a step further and collapses multiple consecutive forward-slashes in
// localized names into a single forward-slash. That means, using 'https://foo'
// as an example, an app with a display name of 'https/foo' is created on
// MacOS and 'https foo' on Windows. By stripping away the schema, we will be
// greatly reducing the frequency of apps having weird names. Note: This
