About Italian letters
Italian mostly uses the grave accent, with the acute on é in words like perché. Accents on capitals are often written with an apostrophe (E') informally but È is correct.
The Italian layout has à, è, ì, ò, ù as dedicated keys and é on Shift+è.
On a Mac, Option+` then the vowel gives the grave accent.
