Old English
Modern editions of Old English manuscripts generally introduce some additional conventions. 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. (In some older editions an acute accent mark was used for consistency with Old Norse conventions.) Additionally, modern editions often distinguish between velar and palatal c and g by placing dots above the palatals: c, g. The letter wynn is usually replaced with w, but sc, eth and thorn are normally retained (except when eth is replaced by thorn).
