> alphabet if the only requirement is that the data has to be readable by a machine its the only requirement because 1. it's only meant for OCR 2. it's clear that it won't be used by only OCR but at least also human interacting with the system, potentially phone calls passing this information by voice, and anyone who can't pronounce the original spelling. For fairness if you e.g. didn't sing at all in your life are somewhat tone deaf and now are expected to pronounce a asian you probably have to spend days or more until you can do so (just as a extreme example).
