A char can hold a single character only  a character literal is a single character in single quote  i e    amp   - if you have more characters than one you want to use a string  for that you have to use double quotes   case   amp  amp

Here s an example    char myChar        string myString           Chars are delimited by single quotes  and strings by double quotes   The good news is C  switch statements work with strings   switch  mytoken        case                 Something here          break      default            Handle when no token is found          break

This is because  in C   single quotes      denote  or encapsulate  a single character  whereas double quotes      are used for a string of characters  For example   var myChar         var myString

I believe you can do this using a Unicode encoding  but I doubt this is what you really want   The    is the unicode value 2A76 so I belive you can do this   char c     u2A76     I can t test this at the moment but I d be interested to know if that works for you   You will need to dig around for the others   Here is a unicode table if you want to look   http   www tamasoft co jp en general-info unicode html

You cannot treat    or    as chars  since they are not chars  but a sequence of chars   You could make your switch   case work on strings instead
