Bug in webdav servlet?
Background:
We are handling lots of documents based on slide cm, maitaining them
using the webdav servlet.
As our users sometimes 'cut and paste' a title from their text editor to
the metadatas, there can sometimes be unusal characters, like the funny
microsoft opening and closing - " -
Today i tried to list the metadatas of a few documents and i had the
surprise to discover it has become impossible to do. The servlet is
responding things like this:

Somehow slide allowed users to set a property to a value which it is
unable to send back later. The problem is quite big as this make the
concerned document unmaintainable (webdav clients are issuing a propfind
before issuing a proppatch). Is it possible to easily ask webdav to
protect the text (using CDATA instead of TEXT for example)?
Thanks for followup
