    Write a function that generates a single-character credit rating identifier by processing a string of encoded credit assessment factors, where the identifier is determined by summing the ASCII values of all encoded factors and performing modulo 26 on the result to map it to a letter grade. The input string contains normalized credit factors where each character represents different credit assessment parameters including payment history, utilization ratios, and account behavior scores. The resulting character serves as a simplified credit rating classification for quick reference in banking systems.
