That's not what the Emacs info files do.  They prefer American English 
conventions for ordinary text, including quoting “like this” for 
ordinary top-level text.  And they prefer single quoting at the top 
level ‘like-this’ for quoting code.  There's no ambiguity in practice, 
as ordinary quoted text does not quote code in the manuals.  Emacs doc 
strings are similar, so there won't be any ambiguity in practice there 
either.

Yes, it's @code{whatever}.

No, @code{foo} is transformed to ‘foo’.
