[IMHO bottom post is clearer, I think]

The value is:

Value: 
(("article" "\\documentclass[11pt]{article}\n\\usepackage[utf8]{inputenc}\n\\usepackage[T1]{fontenc}\n\\usepackage{graphicx}\n\\usepackage{longtable}\n\\usepackage{hyperref}"
  ("\\section{%s}" . "\\section*{%s}")
  ("\\subsection{%s}" . "\\subsection*{%s}")
  ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
  ("\\paragraph{%s}" . "\\paragraph*{%s}")
  ("\\subparagraph{%s}" . "\\subparagraph*{%s}"))
 ("report" "\\documentclass[11pt]{report}\n\\usepackage[utf8]{inputenc}\n\\usepackage[T1]{fontenc}\n\\usepackage{graphicx}\n\\usepackage{longtable}\n\\usepackage{hyperref}"
  ("\\part{%s}" . "\\part*{%s}")
  ("\\chapter{%s}" . "\\chapter*{%s}")
  ("\\section{%s}" . "\\section*{%s}")
  ("\\subsection{%s}" . "\\subsection*{%s}")
  ("\\subsubsection{%s}" . "\\subsubsection*{%s}"))
 ("book" "\\documentclass[11pt]{book}\n\\usepackage[utf8]{inputenc}\n\\usepackage[T1]{fontenc}\n\\usepackage{graphicx}\n\\usepackage{longtable}\n\\usepackage{hyperref}"
  ("\\part{%s}" . "\\part*{%s}")
  ("\\chapter{%s}" . "\\chapter*{%s}")
  ("\\section{%s}" . "\\section*{%s}")
  ("\\subsection{%s}" . "\\subsection*{%s}")
  ("\\subsubsection{%s}" . "\\subsubsection*{%s}")))


I understand that there is a problem here. It should not have 'utf8'
hard-coded.

I removed all LaTeX headers for article except the documentclass
line, i.e I have:

	LaTeX class: article
	LaTeX header: \documentclass[11pt]{article}
	Levels:
	...

Now I've a different behavior. First export and second export are still
different, but the inputenc AUTO feature is working. I attach the two
outputs.

[I'm running org-mode from a cloned Git repository, checked out the tag
7.01g].
