If this must be like shell quoting then you also need to allow quoting

These routines were never meant to be shell quoting (which is silly since
it is a Runtime lib call, not a shell). I also don't see the point why it
should be expanded to do shell

I suspect that the oggenc command is failing
because TProcess behind the scenes is splitting

Yes, indeed. It is also mentioned on the WIKI:

At least IMHO, having to quote the entire parameter string, not just the

I am pretty sure that I have had to deal with this in the past on unix,

I can't really answer you regarding why ExecuteProcess doesn't work.
But just wanted to ask: Have you thought of trying TProcess instead? I
normally execute any external programs via TProcess with good results
