Inter-qube text copy/paste loses some (but not all) Unicode chars

[Kelly Dean]

In a qube in Qubes 4.0, copy the following 3-character Unicode string to the clipboard:
U201C U2013 U201D
That's code for:
left double quotation mark, en dash, right double quotation mark
In utf-8, it's:
e2 80 9c e2 80 93 e2 80 9d
It represents this (if your email client supports utf-8, just copy this directly):
“–”

Then do:
ctrl-shift-c
ctrl-shift-v

Then paste to see the result: the second char is lost. The clipboard now contains only the first and third chars (U201C and U201D).

However, if the clipboard contains just one char, U2013 by itself, then Qubes copy/paste doesn't lose it. It loses U2013 only when it occurs in combination with other chars.

U2014 (em dash) has the same problem as U2013.
U03B1 (Greek alpha) doesn't have the problem.
I haven't tried other chars.

To work around this problem, I have to save the text to a temp file, then use qvm-copy (which doesn't lose any chars), then open the file in the target qube, and copy the text from it.
