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.
