I have the following code:
cout << \"String that includes a £ sign\";
However, the £ sign is not being recognised by the compiler, an
£ does not have an "ASCII code" - ASCII is 7 bits (0..127). There are various extended 8 bit characters sets which include £ but there is no single standard for this and the £ symbol may have various different values in different environments. You should probably be using Unicode if you need international symbols with maximum portability.
