Once upon a time, the criterion for the level of referencing and specificity in an RFC was "everyone, or at least everyone competent to use the spec, knows what one is talking about". Being pedantic for its own sake or on principle was not considered useful or desirable. If anyone is writing code that uses Unicode and doesn't know what a control character is, they are in much bigger trouble than this document can fix. And "C0" and "C1" are defined in Unicode as the names of parts of blocks. I'll make this change, but would encourage everyone to think carefully about whether we really want to go in the direction I think it represents. john
