For the simple use in the ICS demos this simple class is sufficient and 
backward compatibility with early Delphi  versions is simple as adding 
{$IFDEF UNICODE} to the override functions.

 TMyUnicodeIniFile = class(TIniFile)
   function ReadString(const Section, Ident, Default: string): string; 
   procedure WriteString(const Section, Ident, Value: String); override;
   constructor Create(const aFileName: string);

In old Delphi versions use regular ini files, in D2009 check for the BOM 
presence, and when creating new ini file, add the BOM.
Old Delphi saved ini files will open correctly in D2009 compiled demo too.

In what situation you need to convert these files from code?
