AFAICT the string in the original snippet is

—.?-;,:“”‘’–— */()[]{}|<>!`~&…

What I haven't figured out is why there are two long dashes; perhaps
someone added the one at the beginning because they couldn't see
the one in the middle. And why the space after the latter?

The following gives the hex in case this message is garbled.
