Sometimes I need to bring data into a string, and need to be able to treat it as an actual "string", but don't actually care if the entire thing is technically valid UTF-8 or not, don't care if invalid bytes don't get preserved right, and can't have any utf exceptions being thrown regardless of the input. Yea, I know that's sloppy, but sometimes that's good enough and proper handling may be far more trouble than what's needed. (For example: Processing HTML from arbitrary URLs. It's pretty much guaranteed you'll come across stuff that's wrong or even has the encoding type improperly set. But it's usually more important for the process to succeed than for it to be perfectly accurate.)
Far as I can tell, this seems to currently be impossible with Phobos (unless you're *extremely* meticulous about watching what your entire codebase does with the data), which is a major pain when such a need arises. Anyone have a good workaround? For instance, maybe a function that'll take in a byte array and convert *all* invalid UTF-8 sequences to a user-selected valid character?
