Ok, old fixed-2-byte UCS2 is certainly even worse than UTF16, so no argument on that side. I was more wondering who actually *does* this, but it sounds like it was a mostly just that we used to do the old-style UCS-2, and this is extending it to the slightly less broken "extended UCS-2" aka UTF-16. I'd just have liked to see some more background in the logs, because this seemed to me such an odd change to do that it made me go "why would anybody ever care?". But I guess MS (and maybe even OSX) _)still_ haven't gotten the memo on utf-8 and actually use UTF-16.. Oh well. Linus
