It seems to be a modification of French Word Names, in this context of Bienveillance (goodwill, favor, kindness, obligingness, courtesy and so on)
IMHO-too much of the good, considering "the effort", if you had to sign with this never-ending name.
Nevertheless, I can see make the use of this name spelling in the French way, as well as Lafayette, Chardonnay or D'Artagnan.
And therefore only for girls, for boys too womanly tender look.
Nns would almost certainly
Benny,
Bennie, Lancy or
Vivi.
