Thank you KlausG, I'm been able to execute read/write query on the DB from command line following your instructions. Using -- require 'odbc_utf8' -- I've UTF-8 result that can be converted in iconv. Same way, translating the string before the prepare statement it is ...the right string! :-) Now, can I suppose that rails use -- require 'odbc_utf8' -- ? I don't think so! Let's go looking for this switch... -- Posted via http://www.ruby-forum.com/.
