CSV export has been very improved in 1.10, and many errors in 1.9.x have been fixed on 1.10, and this one might have been fixed on 1.9.7 (it works for me, with spanish and catalan caracters on it).

Plus try again with 1.10 when it's released (it may come out shortly, in the following months). Or request specifically some coder to backport the fix on 1.9, if not fixed yet for your case with latest 1.9.x (currently 1.9.7)
