texi2dvi, @appendixsubsec and utf-8

[Karl Hammar]

When running

 $ make web > log 2>&1

i get:

 ./fdl.pdftexi:371: Undefined control sequence.
 <argument> SUPPLÃ<89>
                   MENT : comment utiliser cette licence pour vos documents

when it tries to run

 texi2pdf --batch  lilypond-program.pdftexi

in

 Documentation/fr/user/out-www

The lines in fdl.pdftexi is:

 @page
 @appendixsubsec SUPPLÃ<89>MENT : comment utiliser cette licence pour vos 
documents

Copying SUPPLÉMENT to two lines below makes the error message go away...

Soo, what is going on, cannot you have utf-8 chars in arguments to
@appendixsubsec, is my texi2pdf broken, or what?

 $ texi2pdf --version | head -1
 texi2dvi (GNU Texinfo 4.8) 1.34
