No different as UTF-8 in principle. Base routines keep surrogate pairs
intact if you don't use them wrongly.

And a char is 8 -bit the granularity of UTF-8 without surrogates. IOW it is
orthogonal.

No it doesn't, Windows supports surrogates, and so does afaik Tiburon. It is
just that they chose the granularity of [] to be the granularity of the
encoding rather than char based.
