What if you check out a fresh workink copy, and make sure that locale is
always the same in all operations?

I did some experiments, and it worked when I use WC always with the same
locale.

This worked for me with LC_CTYPE=lt_LT.UTF-8 (and ru_RU.UTF-8 or en_US.UTF-8
should be fine, I guess)

When I change locale to de_DE@euro, and run any svn command in the WC that was
created using UTF-8 locale, svn hangs....

'strace' shows that it hangs on a call:
lstat64("./ÀöÌÃ
so, yes, there is a problem with UTF-8 links. Maybe even in libc?

However, if _first_ set locale to de_DE@euro, then a) check out a fresh
working copy b) run your commands, it works fine again.

It works also works if the repository was created with one locale, but client
runs under different locale. It is only important that if you check out your
WC with locale de_DE@euro, you stick to this locale throughout.

The other way round works as well -- I can create repository under utf-8 and
check it out under iso8859-1 (de_DE@euro encoding), provided I do not have
lithuanian characters in my filenames ;)

(It should work, since, as the Subversion Book says, in a repository
Subversion keeps everyting in UTF-8 encoding anyway -- very nice ;)

It seems that it is subversion _client_ that does not tolerate a change of
locale in the middle of the work. But this is a problem with locales, not
with subversion, I guess...
