A Screenshot of the Data, as Rendered inside Klipper's GUI

SUMMARY

Plasma Integration's "Copy to clipboard" entry enters unusable data into Klipper.

STEPS TO REPRODUCE

1. Visit https://mdn.github.io/dom-examples/web-share/.
2. Select "Share MDN!"
3. Select "Copy to clipboard".
4. Invoke Klipper, and/or attempt to paste.

OBSERVED RESULT

Klipper appears to contain binary data which cannot be pasted into any text entry area.

EXPECTED RESULT

Klipper should contain a UTF-8 URI.

Can confirm.

So this issue happens under X11 as well? Then it’s not what I thought. Under Qt Wayland a URL isn’t implicitly added as text to the clipboard whereas Qt XCB does.

Behavior on X11: entry in Klipper is neither text nor URL but looks like broken images.
Pasting (e.g. into KWrite) results in

Clipboard: Set clipboard text, too, if applicable

Purpose has no proper API contract for sending just text, it's all sent
as part of "urls".

Try to guess what is an URL (we want to be tolerant in the parser since
we don't really know how strict the input will be) and only set that as URL
and also set everything as text.
