Rails, Redmine, Mysql and SQL Server encoding problems

We had redmine working with mysql (and mysql works fine with utf8). Now we needed to migrate the database to SQL Server (开发者_如何学Pythonlatin1 is the default for us). The data acentuation is ok in SQL Server after the migration, but in the browser, data coming from the database is showing ? in the acentuation place. What could be the solution to show characters correctly in the browser?

HTML encode it. Browsers support HTML only, and HTML says all non-english characters are to be specially coded.
