Characters in the extended ASCII set are not supported by MATLAB fscanf (and I would presume fgets as well). I spoke with MATHWORKS support earlier this year when I encountered the same issue. There is a feature request from last year about this but the more people that ask for it, the more likely it will be implemented.

You may have better luck using fread instead of fgets but I have not tried that.
