Thanks.  Lets say that I never want to use the FrontEnd and don't want to
use any escaped characters (i.e. \[....]) because they are a pain to write
and format within command line mathematica.

 Is there a list of kosher symbols that are allowed?  In C, for example, it
would be all the alphanumeric characters, _, and maybe a few more.
