Hello, i have run a dichotomously scored multiple choice test in Conquest (version 4.5.2). I checked the itn.file and found some strange symbols instead of response categories, e.g., "ï", "»" and "¿" (see attached file). This affects the absolute frequencies per response category. It looks like Conquest has read the datafile incorrectly, but i cannot find any problems in the datafile (attached, too). What may have caused this problem? Greetings, agrado.
