.dir-locals.el works for setting virtualenv on Linux/OSX with Jedi, but not Windows

Hi:

Been trying to find a solution to this issue but to no avail.

Basically, I'm trying to be able to use Emacs and Jedi for Python completion, but on a project-specific basis.

I've seen some of the scripts out there like kenobi.el and another one which I can't remember the name of, but I also saw a note about just having to make a .dir-locals.el file with the following code in it:

((nil . ((python-shell-virtualenv-path . "/home/yliangsiew/Scripts/venv"))))

Which works great on OSX/Linux! I get my completions going and everything. However, on Windows, this doesn't seem to work; if I check the value of jedI:server-args, it seems correct (where the --virtual-env does point to my virtual environment on Windows), but I can't get any completions from that virtual environment, and it still seems to be catching packages even from my system Python that are not in the virtual environment.

The only way I have managed to actually get Jedi on Windows to add paths to packages to be used for completion thus far is setting it manually in my emacs init, like so:

  (setq jedi:server-args
      '("--sys-path" "C:/Programs/Maya-devkit/win/devkit/other/pymel/extras/completion/py"))

But obviously I don't want to have to do this, since this would be global and no longer project-specific.

Is there any hint of why this .dir-locals.el method would not work on Windows or something I can do to fix it? I've tried using forward/back/escaped slashes pointing to the virtualenv to use in question, and on multiple workstations; it just doesn't seem to work on Windows for some reason.

Would really appreciate any assistance!
