The following filename is valid now: "x ¬ £ % & + ; x.txt" This was a restriction imposed by WebDAV, but the encoding of the repsonses is working well and these restrictions be removed as a result. Fixed AR-1281: WebDAV upload was assigning incorrect encoding I added a bean 'charset.finder', which can be fetched from the MimetypeService. Various pluggins now exist to decode a stream and figure out what the encoding is. WebDAV and CIFS/FTP are now hooked into this so that they guess a little better. Fixed others: Added retrying transactions to WebDAV. Read/write transactions for WebDAV. git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@6073 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
