Delphi automatically converts between AnsiString and WideString, from PWideChar to WideString, and from a zero-based array of WideChar to WideString. It is nice problem demonstration. In any case, Char is WideChar in D2009+, so SizeOf(Char) is 2 not 1, so you are allocating memory for your AnsiString for only 1/2 of the file data, but then reading the full file into that memory.
