A flourish of approval (goedkeuringskrul) or curl (krul) is a Dutch symbol, analogous to a check mark. It indicates approval, and is mostly used to grade schoolwork.
The krul first appeared in the early 19th century together with the rising bureaucracy in the Netherlands. [1]
The symbol is rarely used outside of the Netherlands apart from the Dutch Caribbean islands and former Dutch colonies such as Indonesia, South Africa, Suriname.[ citation needed ]
Despite its wide usage throughout the country and its former colonies, there is no Unicode symbol for it. [2] [3] [ unreliable source? ] Similar to a dele, it may be substituted with the German penny symbol, ₰.
