Ideally it should. Practically it doesn't. Instead it truncates it for
you. (More likely, it doesn't handle NUL at all and gives you the
entire string, but since it's a C string, it stops at the first NUL
and the remainder goes unused..)

I couldn't think of a pure GUI example, but this bit of Terminality
will get you a nice test string you can paste into anything:
python -c 'import sys;sys.stdout.write("foo\x00bar")' | pbcopy
I tested it with Safari by saving my gmail page and pasting the result
into the save panel. "foobar" read the save panel, "foo" read the
resulting file. So it works fine to test.
