# [Jelly], 3 bytes

    ‘Ọß

### How it works

    ‘Ọß  Main link. Argument: x. Implicit first argument: 0

    ‘    Increment x.
     Ọ   Cast to character.
      ß  Recursively call the main link.
         Jelly uses TCO, so the first cycle finishes successfully before entering
         the next one.

In the second iteration, we try to increment a character, which Jelly doesn't support atm.
