ead on Boingboing.net, the directory of wonderful things. In 1962, the interrobang, was introduced by the New York publishing establishment as “a twentieth century punctuation mark”. The interrobang combined the functions of a question mark and an exclamation point. I must admit I had never heard of the interrobang and searched for a picture of the thing in Google
This is what it looks like. The next link took me to a History of Punctuation which shows quite a lot about punctuation in different languages. There I learned another name for the paragraph symbol. It’s called the pilcrow. History of Punctuation also warns you against mixing up punctuation signs and glyphs. A good read!
