+@c The funny quoting below is to make the printed version look

   One common way to quote is the typewriter convention, which quotes
 using straight apostrophes @t{'like this'} or double-quotes @t{"like
 this"}.  Another common way is the curved quote convention, which uses
-left and right single or double quotation marks @t{‘like this’} or
-@t{“like this”}.  In text files, typewriter quotes are simple and
+left and right single or double quotation marks `@t{like this}' or

+The curved single quote characters are U+2018 LEFT SINGLE QUOTATION
+MARK and U+2018 RIGHT SINGLE QUOTATION MARK; the curved double quotes
+are U+201C LEFT DOUBLE QUOTATION MARK and U+201D RIGHT DOUBLE
+QUOTATION MARK.  On text terminals which cannot display these
+characters, the Info reader might show them as the typewriter ASCII
+quote characters.

   Electric Quote mode makes it easier to type curved quotes.  As you
-type characters it optionally converts @t{`} to @t{‘}, @t{'} to @t{’},
-@t{``} to @t{“}, and @t{''} to @t{”}.  It's possible to change the
+type characters it optionally converts @t{`} to ‘, @t{'} to ',
+@t{``} to ``, and @t{''} to ''.  It's possible to change the
 default quotes listed above, by customizing the variable
 @code{electric-quote-chars}, a list of four characters, where the
 items correspond to the left single quote, the right single quote, the
 left double quote and the right double quote, respectively, whose
-default value is @code{'(?‘ ?’ ?“ ?”)}.
+default value is @code{'(?@r{`} ?@r{'} ?@r{``} ?@r{''})}.
