What diacritical mark was added to Te Atatu in 2008?
Macron (diacritic) A macron ( ) is a diacritical mark: it is a straight bar (¯) placed above a letter, usually a vowel. Its name derives , since it was originally used to mark long or heavy syllables in Greco-Roman metrics. It now more often marks a long vowel. In the International Phonetic Alphabet, the macron is used to indicate a mid-tone; the sign for a long vowel is instead a modified triangular colon ⟨⟩ .
Double acute accent The double acute accent ( ˝ ) is a diacritic mark of the Latin script. It is used primarily in written Hungarian, and consequently is sometimes referred to by typographers as Hungarumlaut. The signs formed with diacritic marks are letters in their own right in the Hungarian alphabet (for instance, they are separate letters for the purpose of collation).
