    Design a function for the bank's credit scoring system that converts a customer's financial behavior string into a single classification character by summing the ASCII values of all characters in the financial data string and performing modulo 26 operation, where the resulting character serves as a compact credit grade identifier. The financial behavior string contains encoded information about payment history, credit utilization, and account age, and the output character will be used in the bank's automated loan assessment process.
