Question mark
In the early 13th century, when the growth of communities of scholars (universities) in Paris and other major cities led to an expansion and streamlining of the book-production trade, punctuation was rationalized by assigning Alcuin's stroke-over-dot specifically to interrogatives; by this time the stroke was more sharply curved and can easily be recognized as the modern question mark.
Kitemark
The Kitemark was originally conceived in 1903 as a symbol to identify products manufactured to meet British Standards' specifications. "Kitemark" came from the kite shape of the graphic device which was drawn up – an uppercase B (for British) on its back, over an S (for standard), enclosed by a V (for verification).
