This function gets the character at the current cursor position and returns it.
Note that the character can also be a special character composed by the MakeConsoleChr()
function. To decompose such characters into their constituents, you can call the
DecomposeConsoleChr() function. See DecomposeConsoleChr for details.
You must enable advanced console mode using EnableAdvancedConsole() before you
can use this function. See EnableAdvancedConsole for details.
