I now think that the rectangle containing four small zeros is displayed for the ascii code 11 (hex or dec?)
That is B means an undisplayable ASCII "character".
Dec 11 is VT Vertical Tab
Hex 11 is DC1
So the original (without shifting) that is dis[layed seems to be:
Length: 16, Data:  (VT)000phoenix.pcx0 or Length: 16, Data:  (DC1)000phoenix.pcx0
whereas, what it should be is:
Length: 11, Data:  phoenix.pcx
