It was already possible to _paste_ (with Ctrl+v) the content of the computer clipboard on the device. Technically, it injects a sequence of events to generate the text. Add a new feature (Ctrl+Shift+v) to copy to the device clipboard instead, without injecting the content. Contrary to events injection, this preserves the UTF-8 content exactly, so the text is not broken by special characters. <https://github.com/Genymobile/scrcpy/issues/413>
