I'm afraid it is still true.  After doing a C-h f c-mode, apparent
quotes were in the buffer.  Checking them with C-u C-x =, they were
indeed curly quotes, but were displayed the same as ASCII quotes.

Currently, my terminal is not such a one.  It _can_ display curly
quotes, but only identically to ASCII quotes.  `char-displayable-p'
returns 'unicode for them.

The issue is not so much whether a terminal can display curly quotes,
rather it's whether a user wants them to be used or not.
