I don't know very much about Italian, but I was trying to learn a bit, and I came across Jesolo- I was wondering how J's get treated in Italian. I know they aren't native Italian letters, but I can't find how they are pronounced-sites are saying that "Jesolo" is read like "Yesolo" so are all j's pronounced like y's in English?
In Italian "j" is pronounced like a semi consonant "i" when it occurs between vowels or at the beginning of a word (e.g. "Ajaccio", "Jacopo"); otherwise it is pronounced like an "i" when it occurs at the end of a word, typically as the plural of some words ending in "-io" ("varj", plural of "vario") (1, 2).
As Rmano pointed out, an alternative to "j" for the plural of some words ending in "-io" is circumflex "î". The use of "j" is more ancient than "î" but today they are both not much in use anymore (anyway, I still like the use of "î", I think it is still considered erudite Italian and it still has its function).
Note that Italian "y" is pronounced just as "i" (3).
