I think the clipboard should already take care of charset conversion?
If it does not, that should probably be fixed instead.

They should be escaped / substituted.

If they are not, please file a bug.

If there is a problem which you are experiencing it should be taken care of.
I am just not sure if the solution of trimming it all to 7-bit ascii is
the preferred one. IMO other fixes should be explored before using this
sledgehammer approach.

I am not involved in the server development, so other people may know
better what's required.
