I included this patch, but it doesn't change anything for me.
After the system call the \uff41 character is always broken up in two
characters.
The problem is that x11_export_final_selection() only works for latin1.
Otherwise it just messes up the cut buffer.
We could avoid putting an invalid string in the cut buffer. Then when
there is a clipboard manager running it hopefully takes over the lost
selection text. I'll make a patch for this.
The only other solution I can think of is saving the owned selection and
restoring it after system() finishes. We would need to check that the
command executed by system() did not change the selection.
