They’d be better off providing standard free functions that can operate on any bucket of bytes claiming to be UTF-8 (allowing operations like iterating over complete composed sequences, creating normalization forms, erasing or inserting based on ranges of composed character sequences, etc.). I don’t want to be forced to create a std::string for example. The bytes might be an incomplete stream as well, e.g. requiring processing up to the last complete thing, detecting invalid sequences.
