not sure if this helps, but

,---------------------------
| (integerp ?a)
| t
| 
| (characterp ?a)
| t
| 
| (format "%s %s %s" ?a?b?c)
| "97 98 99"
`---------------------------

so 

,--------
| (1+ ?a)
`--------

might do the job if you find a way to make Emacs to make Emacs print a
character as String (its char representation, not its integer
representation.

This does not work:

,---------------------------
| (number-to-string (1+ ?a))
| "98"
`---------------------------
