They do hint at, but don't examine from a technical perspective some of the strangeness associated with dingbats. For example, 'n' in an Office application was/is mapped to a picture of a skull, even though a skull has a true Unicode value. Bullets and other symbols aren't just 'clipart', they're used to structure documents, and a lot of problems in document creation/management--especially cross platform--are related to how these situations are handled. Modern emoji where :) maps to a Unicode value of a smiley face add another layer. Perhaps this wasn't the best article, but I think knowing a bit about the pre-computer history, and the early computer history is important to understanding some of the difficult problems that emerge in application development.
