... which brings me to another point: in a hypothetical future when we

without copying the darn thing, what should hypothetical operations to
mutate the string's buffer do?
We need external iterators that store the byte index of the current
code-point as part of their state.
Update operations would then take that iterator as a parameter, so that
they'd know where to start mutating from.
Then it becomes a case of carefully shuffling the correct number of
bytes around, bearing in mind that a unicode code-point may be anything
from one to four bytes long.
Or are you talking about memory management?
The current OUString class allocates a new character buffer for every
mutation, I assume we'd keep that strategy.
