Unable to rename a directory from English to T.Chinese

Hi all,

This problem was reported from a user, and I confirmed it.

The recipe:

  svnadmin create --fs-type fsfs SVN_ROOT
  svn co file://`pwd`/SVN_ROOT foo
  cd foo
  touch BugReport
  svn add BugReport
  svn commit -m "A new file"
  svn mv BugReport 'Bug¤Î«Øij'
  svn commit -m "Rename a file to TC name" # Works fine.
  svn rm 'Bug¤Î«Øij'
  svn commit -m "Remove a TC-named file"
  svn up
  svn mkdir BugReport
  svn commit -m "A new directory"
  svn mv BugReport 'Bug¤Î«Øij' # Rename a directory to TC name. It barks.

If a file's name is English, and renamed to Big5, it works just fine.
If do the same operation to a directory, it fails:

  plasma@plasmanb:~/tmp/xyz/foo(0)> svn mv BugReport 'Bug¤Î«Øij'
  subversion/libsvn_subr/utf.c:363: (apr_err=22)
  svn: Can't recode string

And there are two directories in the WC:

  plasma@plasmanb:~/tmp/xyz/foo(1)> ll
  total 6
  drwxrwxr-x 7 plasma plasma 512 2 22 23:14 .svn
  drwxrwxr-x 3 plasma plasma 512 2 22 23:14 Bug¤Î«Øij
  drwxrwxr-x 3 plasma plasma 512 2 22 23:14 BugReport

Since renaming a file works fine, I think it's a bug in Subversion.

My platform is FreeBSD, and the one who reported this problem uses
Linux. Both of us use Subversion 1.1.3. And locale settings from my
FreeBSD box:

  plasma@plasmanb:~/tmp/xyz/foo(0)> env | grep LC
  LC_TIME=zh_TW.Big5
  LC_CTYPE=zh_TW.Big5
  LC_MESSAGES=zh_TW.Big5
  LC_ALL=zh_TW.Big5

Below is backtrace from gdb:
