Write File With Utf-8

Solution 1:

I solved this problem!

FileOutputStream os = new FileOutputStream(sdCardFile);
        os.write(0xef);<-!!!!!!!!
        os.write(0xbb);<-!!!!!!!!
        os.write(0xbf);<-!!!!!!!!
        CSVWriter writer = new CSVWriter(new OutputStreamWriter(os), ';');
writer.writeNext(HEADER);
...
writer.writeNext('something data');
writer.close();

Solution 2:

I am not sure if this will help, but maybe formatting the string to UTF-8 this way can help:

bufferedWriter.write(newString(machinists.get(i).getLastName().getBytes(), "UTF-8"));

And similarly for the headers.

Edit:

Another thing you can try is to add " for all the values and , as the delimiter (csv stands for "comma separated values" after all):

"1","Аркаев","10","7","6","5","0","6",
