    Create a function that generates a single-character route classification code by summing the ASCII values of all characters in a delivery route's identifier string (containing checkpoint and condition markers) and taking modulo 26 of the result. The resulting character will be used to quickly categorize and group similar delivery routes in the fleet management system's optimization algorithm.
