We now have a couple of mbstring functions which have fast paths for strings marked as 'valid UTF-8'. Later, we may likely have more. So that these fast paths can be used more frequently, mark UTF-8 strings emitted by mbstring as 'valid UTF-8'. This is always a correct thing to do, because mbstring never returns invalid UTF-8 as the result of a conversion (or similar) operation. Internally, we do have a conversion mode which deliberately emits invalid UTF-8 in some cases. (This is done to prevent unwanted matches when we are converting strings to UTF-8 before performing matching operations on them.) For such strings, don't set the 'valid UTF-8' flag. It probably wouldn't hurt anything to set it, because strings generated using that special conversion mode should *never* be returned to userland, and I don't think we do anything with them which cares about the IS_STR_VALID_UTF8 flag... but still, it would likely cause confusion for developers. |
