Encoding::CompatibilityError

[combab0]

I just installed vagrant and virtualbox as instructed chapter 2. I got stuck at boot up vagrant development environment.. I'm working on Windows 8 (x64). is this issue known one? if there is anyone know about this problem please let me know how should I do. but I know that actually it's caused by ruby ;(
