Terminal emacs woes: paste julia output gives char-or-string-p error, \u2502 displays, etc

I am sure—this is not a julia issue. I had just hoped that others had run into the same problem and solved it. (I often work on a remote terminal, rather than a GUI, which is why this is very inconvenient. thanks, antoine, too: it is a weird combination problem of iterm2 and term-emacs, then…grrr.)
