How can i export a file named "a[.txt" by SVN.EXE

How can i export a file named a[.txt by SVN.EXE.
When i try to use svn.exe to export a file whose name consists '[', it will
fail and error info as "svn: URL 'svn://127.0.0.1/test/a[.txt' is not
properly URI-encoded".
If i use TSVN, it can export successfully. But i can only use CLI. So how
could i export such kind of file by svn.exe?
My enviornment is winxp and SVN version 1.5.4 or 1.6.11.
Thanks for your kindly help.
