On MS windows you might look at <start button> <programs> <accessories> <system tools> <character map>. In various "character maps" it is one of the characters whose numeric value is greater than 127. The way to enter a character by its numeric value, on some systems, is, as said above, hold down the alt key and type in the number with the number keypad. This seems to work at least in text editors and some word processors. In the Old Days the ASCII code numbers or Extended-ASCII code numbers, or ANSI codes more recently. Even more recently there is Unicode and ISO 8859-1 latin, and all the other ISO character codings to play with (unless I am mistakenly switching context. Anyone out there more up on the relationship between character maps and character codings and character sets ?? ) Some laptops I've seen have the number keypad keys accessible with the fn key and marked on the keyboard with different colored labels from the rest of the keys.
