Any character that has the top bit clear is potentially valid ascii,
though if you take away the non printing characters there's an
additional exlusion set.
According to http://en.wikipedia.org/wiki...

Testing for character codes with the top bit set should indicate
either katakana or double byte characters. See the chart there for
which ranges are double byte, which are single and which are not legal.
