    In a social networking platform's friend recommendation system, develop a function that processes a user's encoded profile string (containing their interests and connection patterns) and generates a single character match-key by summing the ASCII values of all characters in the profile string and taking modulo 26 of the result. This match-key will be used to group users with potentially similar interests and connection patterns for friend recommendations.
