Non-control characters (characters other than control characters), in this 
case. I wanted to keep things simple and not involve the Unicode database in 
the printer.

(For that matter, [:print:] is a regexp feature and doesn't really define the 
meaning of 'printable', but your question was valid.)

On the other hand, printing all non-controls using the ?X syntax is maybe not 
ideal. Attached is a new patch that uses Unicode properties to select only 
printable base characters.

This patch also removes \a, \v, \e and \d from the characters printed as 
escaped controls.
