The use case is in official PDF of Emacs manual:
https://www.gnu.org/software/emacs/manual/pdf/emacs.pdf
For example look at 1st line of page 39:
"(...) 8 ], C-x 8 { and C-x 8 } insert the curved quotes ’, \ and ",
respectively. Also, a working (...)"

As you can see example of "curved quotes" is showing wrong glyphs for
“ and ”.  They are inserted as e.g. @t{“} in TEXI file, so that
example in PDF can be written in typewriter style, to distinguish them
form the normal text style.  While it looks good in HTML and plain
text, it doesn't work for PDF, because of the font.

There is also different example.  On page 251 there is a value of
'electric-quote-chars' that equals '(?‘ ?’ ?“ ?”).  There, glyphs for
“ and ” should NOT look like doubled ‘ and ’, because it may indicate
that the value is '(?‘ ?’ ?‘‘ ?’’).  That's why I was wrong, when I
said: <<So maybe it's possible to tell Texinfo: "When you see “ or ”
in code environment, print glyph for `` or ''.">>

When I compare PDF with code above with PDF with my code for LaTeX,
glyphs for “ and ” are - I think - the same AND (in PDF from TEXI
file) they are different from ` and ', as well as `` and '' (i.e. `,
``, ', '' are kind of more vertically stretched), which is good.

So, if because '\ecfont' it shouldn't be that difficult to implement,
maybe we could try it?  Then build Emacs manual with it, see if it
looks better.


S. U.

P.S.  If it won't work for some reason, I have alternative solution
which looks good enough, i.e. by using @t{@b{“}}, but I would want to
do this in less hacky way and that is why I'm writing these e-mails.
