The Wikipedia has the following information about this codepoint:
Centuria (Latin:[kΙnΜͺΛtΜͺΚria]; pl.: centuriae) is a Latin term (from the stem centum meaning one hundred) denoting military units originally consisting of 100 men. The size of the centuria changed over time, and from the first century BC through most of the imperial era the standard size of a centuria was 100 men. By the time of Roman Empire, ordo became a synonym of centuria (in the 4 BC it was used for a maniple).
