    Design a function that generates a single-character hash from a user's social interaction data string by summing the ASCII values of each character in the interaction pattern string and performing modulo 26 on the result, where the final character serves as a quick matching identifier in the friend recommendation system's first-pass filtering process. The resulting character should be mapped to the alphabet (A-Z) and used as an initial clustering mechanism for potential friend matches.
