Keyboard mode switching in a script/batch, WIN XP

Ok, so what i would like to have is a script/batch file that would do the following:
- switch keyboard mode
- run GVim with specified parameters
- switch keyboard mode back

The reason for this is that GVim doesn't properly work with ISO-8859-2 with Polish characters, so I needed to install me an additional font and an additional keyboard setting. Before running GVim, I've to switch keyboard mode to the new one, but since I don't want it to be permanent, I'd like to have it automatized.

Any ideas?:)

I have no idea myself, but I'm such it's been done already. Have you tried googling for it? I would be very surprised if nobody's written code to do exactly that.

It might have to be a program, though, not just a script.

Tried googling, couldn't find anything useful.
