I won't count "!*(f ^^/~ ? " as today's word/phrase, but I will take a useful word out of it: "(f" is a shining example of a digraph, which is essentially a letter composed of two separate characters. Oou aside, this type of character appears in English via "ch", "sh", and "ai" among others. Perhaps more notably, it creates actual letters in some languages such as Vietnamese, which treats "ng" and "tr" (among others) as individual letters. Vietnamese even uses one trigraph: ngh.
