I was not just playing with REPL, I tried to compile the code and reloaded the image
(let ((*attribute-quote-char* #\"))
(with-html-output-to-string (*standard-output* nil :prologue nil :indent nil)
    (:html
     (:head
      (:title "title")
      (:meta :name "DESCRIPTION" :content "description")
      (:meta :name "KEYWORDS" :content "keywords")))))

but I still had a single quote in the resulting code.

WITH-HTML-OUTPUT is a macro, so what is relevant is the value of
*ATTRIBUTE-QUOTE-CHAR* at macro expansion time. If you play around in
the REPL, this is obviously different for Lisps which always compile
everything (like SBCL) and Lisps which use an interpreter for REPL
forms (like LispWorks). See chapter 3 of the CLHS for details.
