Someone to test my accordion plugin on Windows?

I've just written my first Musescore plugin for a friend - to add button accordion fingering (or harmonica holes) to a score. It seems to work OK on my Mac, but I'd like to make sure it works on Windows before I submit it - eg. I've had horrible problems with Unicode on Windows before now!
Let me know if anyone is willing to try it out and give some feedback ...
Thanks
Paul
