Ada a matter of fact, yes. Some implementations of streams will use the
size of the base type as the stream element size, no matter what is
specified
for the 'Size attribute.

My project found the only reliable work-around for that compiler was to
convert all bytes to and from characters when using streams.

One more possibility:

type Byte is mod 2**8;

type Byte_Array is array(Positive range <>) of Byte;
