I'm sorry to get back to this now, but I'm reading an introduction to C in 
French where I found:

"Une des particularités du type char en C est qu’il peut être assimilé à un 
entier: tout objet de type char peut être utilisé dans une expression qui 
utilise des objets de type entier. Par exemple, si c est de type char, 
l’expression c + 1 est valide."

Is that the reason why characters are integers in emacs lisp too ?
