No response

Expected behavior:

Then I copy text from far2l (Linux port of Far Manager, gui wxWidgets-based version), to Telegram Desktop, text should be copied fine.

Then I copy text from far2l (Linux port of Far Manager, gui wxWidgets-based version), to Telegram Desktop, text is not copied at all.

In native Ubuntu 23.10 such copy-paste works fine.

It's worth nothing that even a very simple call to gtk fails to place the text in the Windows clipboard:

    GtkClipboard* clipboard = gtk_clipboard_get(GDK_SELECTION_CLIPBOARD);
    gtk_clipboard_set_text(clipboard, "Hello World!", -1);

Implemented workaround on our side. Please run

FAR2L_WSL_NATIVE=1 far2l

to reproduce the bug after this PR is accepted

Also please note that even with GDK_BACKEND=x11 clipboard has problems under wslg under Wayland: you can't copy/paste multi line text. I guess that some kind of \n -> \r\n conversion and vice versa should be added, but I am not actually sure.
