It looks like the buffer is being displayed in the raw-text coding
system (is the first character in the mode line "t"?).  \342\200\234 is
the raw-byte sequence of the unicode character LEFT DOUBLE QUOTATION
MARK (#x201c) and \342\200\231 of RIGHT SINGLE QUOTATION MARK (#x2019).
Does typing `C-x RET r' and at the prompt entering `utf-8' and at the
next prompt `yes' fix the display?
