I recently ran into some problems while using my Teensy 3.0 with a German keyboard layout. The Problem however only occurs on windows machines, on Linux machines everything works fine. It seems that every apostrophe turns into acute accents and sometimes even this "" character I have never seen before.
This is from the layout test run on a Linux machine:

Symbols1: !"#$%&'()*+,-./

And this from a computer running windows 7:

Symbols1: !"#$%&()*+,-./

Here is the environment I am using:

-Arduino 1.0.3 + Teensyduino 1.13 (Linux)
-USB type: "Keyboard + Mouse + Joystick"
-Keyboard Layout: "German"
-Teensy 3.0

I am not really sure if this is even a bug on the teensy side and not on the windows side, but I thought I'd let you know anyway and hope that someone might be able to help me with my problem.
