I don't understand how this can work.
Has each record a flag saying this record was encoded in Windows or MacOS
format ?
Or do you convert all records in one unique format, that is not platform
dependant ?
You have said that strings are stored in the platform specific format. Thus
when I'm on Windows and add my first record, it is stored in Windows format.
Next I go to the Mac and add a second record, stored in Mac format. Next I
go to Windows and read both record. How can you know that the first is in
Windows format and the second is in Mac format ?
Or do you mean that if the .dat file is created in Windows, it is "marked"
as a Windows format file and all records are stored in Windows format, when
I add records in Mac or Windows ?
