OK, the current solr dev version should now work correctly w.r.t. CSV. I ended up rewriting the commons-csv escaping so that normal CSV encapsulation can be handled, but also an escape can be specified for standard backslash style escaping. Leading + trailing whitespace is now also preserved, so one should be able to do direct loading of MySQL table dumps. See the last section in http://wiki.apache.org/solr/UpdateCSV
