The screenshot seems to show the "terminator" terminal.

Since you wrote that it doesn not only happen in one terminal
emulator, it's likely not a terminal-emulator-specific setting as
present in many of them.

Nevertheless one question here: Which terminal emulators did you try
beside terminator? Where all libvte-based? Or was one them e.g. xterm,
lxterm, uxterm, aterm, urxvt or another rxvt variant? (The set of
terminal emulators I mentioned all use fixed fonts by default while
the libvte-based terminal emulators all use vector-based fonts.)

Next idea was non-utf-8 locales, but this looks fine, too:

> Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8)

I tried it on a Debian Jessie workstation, also with LANG=en_US.utf8
and LC_CTYPE=en_US.utf8 with at least terminator and uxterm -- and in
both, the line drawing characters look as expected. See attached screenshot.

Just to be sure: Did you call reportbug in one of the terminals where
this happened?

Since it's the replacement character: Maybe there is the proper font
missing?

Can you paste the output of the following command into a mail to this
bug report?

dpkg -l | egrep "^ii  (x?fonts|ttf)-" | awk '{print $2" "$3}'

If this for some reason doesn't work and you have aptitude installed,
try this command instead:

aptitude search -F '%p %V' --disable-columns '~i ~n "^(x?fonts|ttf)-"'

(Both commands try to list all installed font packages and their
version numbers. At least on my system, they output the same list.)
