Several remarks :
� seems not be be listed (see � w�rmien �, � le w�rm �, � arg�er� now acceptable according to a recent spelling reform).
Population of France is now 61,7 millions (including around 1,7 millions French citizens in French overseas territories), but French is also the native tongue of populations in Belgium, Luxembourg and Switzerland (all in Europe).
Haarmann 1993 figure of 58,1 millions was for Metropolitan France + overseas territories (1990 census).
[PA] Incidently I notice contrarily to French the populations for Dutch and German speakers include the speakers of those languages in several country.
Also for Dutch, I'm not convinced the list of letters is complete in http://www.evertype.com/alphabets/dutch.pdf
Most vowels could take an acute accents I believe : attach�, log� (French words), d��rdringen, g��n, b��ten, dr��ien (stressed syllables, cf. http://www.geocities.com/tinnestaaltroep/tinnepick.html, stressing words graphically is common and (much) more frequent than in written English while stressing words by adding accents is about completely absent in French).
The circumflex also is used : enqu�te, g�ne, f�teren
As well as � in sc�ne (in my Kramers Nederlands-Frans dictionary).
