UTF-8 SVN crash on "zotero/extension" access

I am getting UTF-8 encoding errors on every version of svn I can use on windows. I have tried from cygwin's subversion, a command line subversion application, in addition to checking out from Tortoise SVN. I can't come up with any other ideas.

The file that is posing from Cygwin is:
svn: Can't convert string from 'UTF-8' to native encoding:
svn: trunk/translators/Bibliothe?\204?\128que nationale de France.js

from TortoiseSVN, I am getting an error with the same file:
Error processing command 'readonly' in 'extension\trunk\translators'
Can't set file 'extension\trunk\translators\.svn\text-base\Bibliothèque nationale de France.js.svn-base' read-only:
The system cannot find the file specified.

This is obviously due to UTF encoded files in the repository and it seems neither windows or cygwin knows how to deal with it. Please help, as I can't figure out a way to get the rest of the repository without fixing this problem. Is there a TAR somewhere with the same data?
