I cannot reproduce this on GNU/Linux:

I see that you're running Emacs on Windows, maybe there is something
special to be taken care of on that system.  I find it strange that
you experience this problem only with one engine: I didn't check it,
but I thought that the expansion of file name doesn't depend on the
selected engine.

I'll try to have a look, but not using Windows, it's difficult for me.
If someone else comes up with a solution, please chime in.

Bye,
Mosè
