EDIT: My problem has been fixed or, more precisely, worked around, thanks to help in the comments below. Never figured out what exactly the issue was as it wasn't a problem with my Emacs configuration but with my Emacs installation (which I had originally done via Homebrew).
I am using Emacs 25.0.5 on OS X 10.10.5. For some reason, Emacs displays ‘ ’
and “ ”
only as ' '
and " "
, respectively. The behavior persists in typopunct-mode
(from the Typopunct package), although things like en- and em-dashes display correctly as distinct Unicode characters. The behavior also persists if I use a variable width typeface I am certain has glyphs for curly quotes.
