In this respect, nothing has changed in Delphi 2009. What is different is that the Char type used to be an alias of AnsiChar and is now an alias of WideChar. Every time the compiler sees Char in your code, it reads WideChar. Notice that there is no way to change this new compiler default23.
This is quite a change, impacting a lot of source code and with many ramifications. For example, the PChar pointer is now an alias of PWideChar, rather than PAnsiChar, as it used to be. We'll see how this affects the calls to Windows API functions in a later section in this chapter.
