Or a handmade font ? Do you know some font like this one, with big shapes.

Qu'est-ce que c'est supposé représenter ?

A "c".

why do u suspect this is a font? Do you have more characters than this "c"?

that´s a logotype, not a font =s

Yes, it's a logotype, so it's just the only one characters, but it could be a font, but imho it's a handmade logo and not a real font.
Do you know a font who is similar with this shape ?
