Does the code save the clipping to the clipboard with multiple
formats? e.g. an ascii format, a utf-9 and a utf-16 or even an html
version? I Don't recall how you had to code the clip operation so the
paster can choose the best format to paste. I think mintty does this
so that a text editor can paste the text from the screen, but a html
editor can paste the maked-up text with bolding, underlines, etc.

If you have turned on "Clipboard history" and/or "Sync across devices"
in the Clipboard Settings, in at least some versions of Windows 10,
there is an internet round trip to a Microsoft server that causes a
delay between the copy-to-clipboard operation and when that clip is
available for a paste-from-clipboard operation. If you perform a
Ctrl-C immediately followed by a Ctrl-V, i.e., before the round trip
completes, you will paste the previous clipboard contents instead of
the expected new content.
