Please add Wayland bug workaround

[unxed]

On Ubuntu 23.10 in Wayland session you can't copy text from GNOME Text editor (v.45) to far2l (Far Manager Linux port) GUI (wxWidgets-based) version. Same issue is observed with far2l GUI + Telegram Desktop, latest version. Same bug with KDE text editor, qBittorrent.

The reason is that whose apps expose text only astext/plain;charset=utf-8 or as text/plain;charset=utf-8 and text/plain, but wxWidgets only understand STRING and UTF8_STRING in some aspects of its clipboard API.

Please add an option to monitor clipboard content and if found text/plain;charset=utf-8 without UTF8_STRING, perform conversion on the fly so all apps can see each other formats seamlessly.
