What constitutes a "printable character" is inherently locale-dependent.
Since the OS kernel has to support multiple concurrent locales, it is not
in a position to make a correct determination about character printability.

People who argue that the kernel should "help" the user seem to have
missed out on what is REALLY helpful and to have instead settled on an
overly restricted model of what users need to do.  The UNIX designers
got this exactly right.  The "value added resellers" on the other hand
seem to let marketing yoyos make their technical decisions for them.
