[ros-kernel] String Display Error

[Skywing]

While pages are zero filled by the zero page thread before they are passed
to processes via Nt/ZwAllocateVirtualMemory, you aren't guaranteed a zero
filled buffer if you use, say, the heap functions to allocate memory.  So, I
do not think there is some missing behavior in ReactOS.

Actually there has been consistent behavior in the case of both 
platforms, I think the reason for this is because if I remember 
correctly all strings a zero terminated, so it really doesn't run past 
the end of the string, its just running past the useful part of it, so 
when Windows reads that zero it just puts a blank space but ReactOS puts 
a box.
