The resolution to this problem is currently under discussion on the
dev@apr.apache.org list (as far as MacOSX goes, other *nix are an
entirely different matter and unfortunately won't work without setting
the right encoding).

Exactly. But your solution has a number of implied consequences. When
extending the Subversion design, we're used to hashing out all the
consequences and choose the solution which is the best trade-off of
all problems solved (and new ones created). We're in that phase now.

You don't have to care about the border-cases in Unicode, but if we
don't want to introduce the same problem, but then in reverse (ie stop
working on Windows), we'll have to work through all problems and
solutions before actually doing any coding. This leaves enough
surprise problems to be resolved when we release the Release
