Query: When eth is replaced, what is it replaced by?
Context: (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: ⟨ċ⟩, ⟨ġ⟩. The letter wynn ⟨ƿ⟩ is usually replaced with ⟨w⟩, but æsc, eth and thorn are normally retained (except when eth is replaced by thorn).
