Yes, sizeof(char) is guaranteed to yield 1. However, that tells you nothing
about the bitwidth of char. The types char, int, long may all be aliases for
the same integer type, for example, a 36-bit integer. Untyped memory is best
passed around using void pointers. "char *" is fine too for backwards
compatibility but often requires explicit casts to avoid compiler warnings.
