As long as bit 7 is a 0.
Traditional ASCII only allows/defines the values 0x00 through
0x7f. If that's what is meant by "ASCII", then a file
containting bytes greater than 0x7F is not ASCII.
If all bytes are 0x7F or below, the file _may_ be ASCII, but
there's now way to tell if it _is_ ASCII unless you ask the
creator of the file. It could be Baudot or some other encoding
that doesn't use bit 7. Or, it could just be binary data that
happens to have bit 7 == 0.
