I'm not sure this is correct. You are saying that the compiler counts
bytes in the original file, not in its output (which might be encoded
differently). Do we have conclusive evidence that this is always
true?

??? The same Latin-1 characters encoded in ISO-8859-1 and in UTF-8
will yield a different number of bytes. So I don't think I understand
how can you say the above.
