Details

Develop versions of UTF-8 to UTF-16 and UTF-8 to Latin1 conversions as well as Latin1 range check for UTF-8 that can read from shared memory in the presence of an adversarial second thread of execution without the result being a security bug and use that in decode without a memcpySafeWhenRacy in the case the buffer is a SharedArrayBuffer and the encoding is UTF-8.
