    Write a function that generates a single-character fraud pattern identifier by taking a transaction-location code string as input, where the identifier is computed by summing the ASCII values of all characters in the input string and performing modulo 26 on the sum to map it to a letter in the alphabet. This character serves as a quick reference code for identifying potential fraudulent transaction patterns across different geographical locations.
