Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      Another candidate definition of a systems programming language: Must give you access to a *non-validating* UTF-8 codec.

      That is, one that cheerfully converts U+D800 to ED A0 80 and back, decodes F0 82 82 AC to U+20AC, and ignores the artificial U+10FFFF limit.

      I think I understand your motivation here, but this requirement is a big mistake.

      The ability to process malformed UTF-8 non-destructively is important, but accepting these invalid inputs is neither necessary or sufficient

      Wrong scenario; the one I care about right now is _generating_ invalid UTF-8 without hassle, in order to test another piece of code.

      OK, that makes your original tweet make more sense, but I still think it's a mistake.

      If language is strongly typed and UTF-8/Unicode string is a type, malformed UTF-8 strings (with that type) simply can't come into existence.

          Regardless, making byte strings that would be malformed if you attempt to interpret them as UTF-8 is trivial without lang/lib support.

          c1, f8, and fc never appear in UTF-8; rest are more subtle.
