/** Replace the individual digits in the current string, between startPosition and endPosition (included), with the corresponding Roman numeral symbol (s). The first character in the string is * considered to be in Position 1. Digits are converted individually, * even if contiguous, and digit "O" is not converted (e.g., 460 is converted to IVVIO).
