Examples and Observations:

• "English doesn't have many logographs. Here are a few:

  & % @ £

  We would read those as 'and,' 'per cent,' 'at,' and 'pound.' And in maths we have several more, such as the signs for 'minus,' 'multiplied by,' 'divided by,' and 'square root of.' Quite a few of the special signs in chemistry and physics are logographs, too.
  
  "Some languages consist entirely of logographs. Chinese is the best known. It's possible to write Chinese with an alphabet like the one we use for English, but the traditional way of writing the language is to use logographs--though they're usually called characters when we talk about Chinese."
  (David Crystal, A Little Book of Language. Yale University Press, 2010)

• Logographs in English
  "Logographs are used in many languages, including English. When the symbol [2] is used to represent the word two in English, it is being used as a logograph. The fact that it can also be used to represent the number deux 'two' in French and the number mbili 'two' in Shinzwani means that, although the same sign can be used as a logograph in different languages, the way it is pronounced can be different, depending on the language in which it is functioning as a logograph. Another sign that is used as a logograph in a lot of different languages is the [@]. In contemporary English, it has come to mean at and is used as part of an Internet address. It works comfortably in English to say myname-at-myinternetaddress, but this doesn't work as well in some other languages."
  (Harriet Joseph Ottenheimer, The Anthropology of Language: An Introduction to Linguistic Anthropology, 2nd ed. Cengage, 2009)
• Logographs in Texting
  "What novelty there is in texting lies chiefly in the way it takes further some of the processes used in the past. . . . There are no less than four processes combined in iowan2bwu 'I only want to be with you': full word + an initialism + a shortened word + two logograms + an initialism + a logogram."
