Ok, fine. I can see that working and be useful. Apart from the fact
that we currently do not really have a concept of a per-WC configuration.

But with the default set to the old behaviour please. We don't want
to cause surprises for unsuspecting users.

This knob would have to be in the client config, I guess, and apply
to all working copies during checkout and update. The working copy
would of course need to remember the value of the config knob had
during the initial checkout (this can be stored in wc.db), and would
re-use that value even if the configuration knob is changed.

What if the encoding specified in the config is not supported by
the iconv library? Do we fall back to LANG or ASCII?

Re-encoding all filenames in a working copy would only be possible
via a new 'svn checkout', I guess. Same as resetting LANG and running
'svn checkout' again.

I recall us having had this discussion before, by the way:

Another idea: Introduce a new inheritable property that dictates
what encoding clients should be using for filenames. This would
probably be very easy to mess up when multiple client platforms
are involved, but could prevent problems for users who don't set
up their config or LANG correctly where admins just want this to
work out of the box within their own organisation.

You do. Now please file an issue or send a patch :)

Ouch. I've seen others feel your pain :( It's not very pleasant indeed.
