The modern forms of Latin letters are used, including ⟨g⟩ in place of the insular G, ⟨s⟩ for long S, and others which may differ considerably from the insular script, notably ⟨e⟩, ⟨f⟩ and ⟨r⟩. Macrons are used to indicate long vowels, where usually no distinction was made between long and short vowels in the originals.
