diacritics not importing with RIS filter

Diacritics (accents) aren’t importing correctly when I use the RIS import filter. When I look at the filter in the Import Filter Editor, the box “Contains ANSI characters” is checked under Text Styles, so I’m not sure why it is not working. 

I am using RefMan 11.0.1 in Windows XP Pro. I am trying to use the RIS filter to create a filter for EBSCO Host CINAHL results saved as RIS.

Thanks very much!
