Also note that the tab character has a printable character (although, in most circumstances,
it's ''converted'' to a blank (or a number of blanks).  It's graphic on my computer is &nbsp; <big> '''○''' </big> &nbsp; &nbsp; (a circle). 

Also, only three characters don't have a printable characters, '00'x, ''the'' blank, and 'ff'x.  Of course, this is very
dependent on the '''code page''' being used. -- [[User:Gerard Schildberger|Gerard Schildberger]] 07:06, 17 December 2012 (UTC)
