i will add one thing even logics as formal mathematics language that actually is the nearest to a universal language has become universal quite recently (Boole, Frege, Russell... sorry Winterfox can't help to quote those names)... before it was some kind of juxtaposed mathematical languages (there were aegyptian logics, indian, chinese, arabic... ect)...
and they were not made for emotion...
beside esperanto has never managed to become a "true" language...
some african people have no words/symbols for saying/showing :"snow" and eskimos have many (i don't remember how many exactly right now) for saying/showing "white"...
well even for a computer we can't make a true universal language (even java or ada 95 are not really... C and C++ not at all)...
symbols may work for the Internet because they are few...
a game needs really more if you want to communicate any emotion...
DATD: Thanks for French words it was really appreciated!
Winterfox: sorry for lack of coherence and thanks for the links...
the other one was not working
