I was afraid of that.

I don't see why a property like "encoding" wouldn't work with a smart
client. Some of the files would indicate iso-8859-1; others would be
tagged utf-8.

That won't help, because the conversion needs to happen when the files
come out. I can store the file in iso8859 or utf-8, but I have to
pick one of them. When I check it out into the other environment, the
file won't be interpreted correctly.
