Yes, I tend to do so, especially with software code.
But, al last, we convinced our hardware, marketing and field people
to use Subversion as well. Please don't suggest me to tell them to stop
naming the documents they produce without accents and ñ :-)
I can hear them: 'What the heck? Until yesterday I was able to navigate
with my web browser your repository and all the documents had the names I
gave them. You are telling me now that you are re-naming them? Crazy!'

Done it. No joy :-(

95 % of our uses use TortoiseSVN to check-in and check-out. Many of them
use a browser to surf the repository. In fact, the problems I reported were
found using TortoiseSVN, so the first thing I always do in these cases
is to check the problem with svn command line. In this case,
the observed behaviour was the same.

I cannot imagine a sensible way of using svn mv with the files that are
checked-in with Windows clients and want to check out from Linux clients.

Is there some way to force the Linux server / svn server / svn hooks to use
'Windows' filename convention, whatever it is?

Is there some way to reprocess (dump / load or whatever) the whole
repository in order to make happy both Linux clients and Windows clients
without changing the non-ASCII characters as seen by both clients?

What I was really surprised is to see that the filenames flowing through the
communication channel is not normalised (well, that is just speculation,
am I wrong?). Is there a way to force the clients to convert the names
to same canonical form (e.g., UTF-8) and back to the resident filesystem
convention again?

What are doing my Czech, German and Turk friends in this forum?
