Large object layouts don't fit in a pointer-sized integer and therefore need to be stored in a global instead. However, the way the data was stored in these globals was not correct for buffers that don't have pointers near the end. This commit fixes this issue by using math/big FillBytes() instead of Bytes(). This gets the unicode package to compile on AVR.
