It says `characters' in C11 and C17

standards:
"Description
The fread function reads, into the array pointed to by ptr , up to
nmemb elements whose size is specified by size , from the stream
pointed to by stream . For each object, size calls are made to the
fgetc function and the results stored, in the order read, in an array
of unsigned char exactly overlaying the object. The file position
indicator for the stream (if defined) is advanced by the number of
characters successfully read. If an error occurs, the resulting value
of the file position indicator for the stream is indeterminate. If a
partial element is read, its value is indeterminate."
but indeed `bytes' sounds nicer especially if unsigned char is not
mentioned in the manpage. I sent v2.
