That is normal.

This is not normal.

I created the following TCustomApplication program:

procedure TMyApplication.DoRun;
var
   ErrorMsg: String;
begin
   writeln(getoptionvalue('f','file'));
   Terminate;
end;

When run it prints the correct output:

araminta: >./tc --file='my file is here.txt'
my file is here.txt
araminta: >./tc '--file=my file is here.txt'
my file is here.txt
araminta: >./tc "--file=my file is here.txt"
my file is here.txt

So I doubt the problem is there. What gets printed if you do a

For I:=0 to ParamCount do
   Writeln(Paramstr(i));

Just to rule out TCustomApplication.

You mention TProcessUTF8, that is a complicating factor. 
You then need to see (using strace) what the calling app actually sends.
I suspect the problem is there.

Are you using the new 'parameters' or still the old 'CommandLine' ?
If the latter, then it is a safe bet that the problem is there.
