Thanks for this kind of promising feedback.

Can this aspect also be clarified to some degree from a logical point of view?

* Would you really like to know under which circumstances data processing
  will be faster for a single character instead of using a string pointer
  and corresponding two characters?

* Do you care for a changed memory allocation characteristic?

* Will it occasionally be useful to avoid the storage for another string literal?
