Description: Implements a fast check to determine if a string is Latin1 a byte string Latin1. Can be many times faster than the equivalent regex check. input isByteString regex loop short, one-byte 232M 122M 55M short, two-byte 207M 130M 56M short, invalid 106M 48M 53M long, one-byte 221M 93M 230k long, two-byte 6.7M 913k 186k long, invalid 75M 914k 234k (the larger perf gap there is with concatenated strings)
