// The goal is to copy the byte representation of the input into the output type.
// A single static_cast will try to preserve the value as opposed to the byte representation
// which leads to issues when the input is signed and has a negative value. That will get
// wrapped to a very large unsigned value which is incorrect. To address this, we first
// cast the input to its unsigned equivalent then cast that to the destination type which has
// the property of preserving the byte representation of the input. A simple memcpy seems
// like a viable solution but copying the bytes of a type into a larger type yields different
// results on big versus little endian machines so it's not a possibility.
//
// Why do this? For example take the Latin1 character é. It has a byte representation of 0xE9
// and a signed integer value of -23. If you cast -23 to a char32_t, you get a value of
// 4294967273 which is not a valid Unicode codepoint. What we actually wanted was a char32_t
// with the byte representation 0x000000E9.
