Although they're different encodings, the thing that they are encoding is exactly the same. I kinda wish I could edit "string representation" to "modeling valid strings" or something in my original comment for clarity...

By that logic, you could say ‘“UTF-8” aka “UTF-32”’, since they are encoding the same value space. But that’s just wrong.

		The type is the same, i.e., if you look at a type as an infinite set of values, they are the same infinite set. Yes, their in-memory representations might differ, but it means all values in one exist in the other, and only those, so conversion between them are infallible. So in your last example, UTF-8 & UTF-32 are the same type, containing the same infinite set of values, and — of course — one can convert between them infallibly. But you can't encode arbitrary Go strings in WTF-8 (some are not representable), you can't encode arbitrary Python strings in UTF-8 or WTF-8 (n.b. that upthread is wrong about Python being equivalent to Unicode scalars/well-formed UTF-.) and attempts to do so might* error. (E.g., `.encode('utf-8')` in Python on a `str` can raise.)
