No. The ASCII specification provides for 8-bit ASCII encodings. These are called extended ASCII characters. ASCII is not exclusively 7-bits. That's the entire point. This was proven in the pdf, an extended version of the ASCII standard, that Alex provide a link too. What you (and apparently Alex too) are saying is that because the ASCII standard allows a 7-bit subset of the character set to be used, then a byte and therefore a character as it was defined by Bob Bemer, Hugh McGregor Ross, and Dr. Werner Buchholz is not exactly eight bits, but seven.
