As part of a method I am playing with while learning Ruby I need to be
able to determine which characters in a string are non-printable. What
is the "best" method for determining if a character is printable, such
as an "A", or unprintable, such as a tab?
While I could create a list of printable characters using ranges is this
the best way to do this?
