The only name I know of that has an abbreviation ("Chas.") as opposed to a nickname, though it's seldom used nowadays. Why? It's certainly short enough as it is.
Another common French form of the name is "Charl" The form Charl was carried by several of the French hugenots of whom one Charl Marais Settled in South Africa in the 1820's.
