We tried to introduce support everywhere and it fails. Do we really want to step on the performance gains introduced by recent changes by making all strings unicode ? That doesn't seem like a sensible thing to want, at least right now. Having UString doesn't stop us approaching the problem differently in the future, but it would have to be a very different future to even make sense to me. > If we don't care about complete solution, UString proposal may make > sense at lest as a faster replacement of ext/mbstring. As the RFC states, we are only approaching one problem, the problem that ext/mbstring is not a good API. > > Thanks.
