Of course. A pointer-to-charactertype can be used to access the
individual bytes of any object that occupies the memory location
said pointer happens to point to (Ref: C99 6.3.2.3p7).

IIRC OP's question was, if this is still valid when the p-to-char
was not converted directly from the pointer to the original object,
but "went through" a pointer-to-void. It is (Ref: C99 6.2.5p26,
6.3.2.3p1, 6.3.2.3p7).

Aside: in some sense, a pointer-to-void is just a pointer-to-char
in disguise: it shall, as the authors of the standard put it, have
the same representation and alignment requirements.
