Well, it depends on where you choose to draw the line between text and
what Unicode calls "higher-level protocols" such as markup.  There are
markup schemes in which even newline and space have no meaning,
but it's hard to see why one would want to go so far.  The other
control characters are on a cline from form feed and horizontal/vertical
tabulation down to ^P, synchronous idle (sent on synchronous connections
when it is necessary to keep sending to maintain framing, but there is
nothing to send).
