Thanks for the report. We've checked the problem and found it depend on some Language and Regional settings.

    As we found when retrieving data from data source, Origin is able to get the bytes correctly before converting them according to  local code page settings.

    If select Start->Control Panel->Regional and Language Options->Advanced, set the Language for non-Unicode programs as German(Germany) or English(United States),
    Origin and import and display the data record correctly, but if set as Chinese(PRC), chars will not be imported correctly.

    So please check your Regional and Language settings and try to import the data again. Or would you please show us your Language settings here? Thanks.
