Hello! I'm Italian. In Italy we usually say "piacere di conscerti" or just "piacere", and "piacere mio" is how we reply.
I'd like to know how you say this sencence.
I wish to know people from all over the world (traveling or just living my life) and I'd like to say "nice to meet you" in their own languages.
I think it could be a delightful way to start speaching with somebody new.
In Hungary: "Örülök a találkozásnak!" or just "Örvendek!" :)
Hello Martina!:) I'm from Hungary, so in Hungarian we say it like this: Örülök, hogy megismerhetlek/megismerhetem (informal and formal) or Örülök a találkozásnak :)
Hi!! in Spain we say "Encantado de conocerte" or "Un placer"
In Indonesian: "Senang bisa berkenalan dengan anda"
you read it as it's written. Just like Italian language :)
We say in persian:
خوش آمدی که خوش آمدم از خوش آمدنت
OR
از ملاقات شما خوشبختم
:)
