Java reading cyrrilic CSV file, writing strange characters

Question

This is my java code

(and the whole project has UTF-8 encoding)

public static ArrayList<ArrayList<String>> getCSVContent(String filepath) throws Exception { 
            CSVReader reader = new CSVReader(new FileReader(filepath));
            ArrayList<ArrayList<String>> array = new ArrayList<ArrayList<String>>();
            String[] nextLine;
            while ((nextLine = reader.readNext()) != null) {
                ArrayList<String> list = new ArrayList<String>();
                for (int i = 0; i < nextLine.length; i++) {
                    list.add(nextLine[i]);
                }
                array.add(list);
            }
            reader.close();
            return array;
        }

This is my CSV File:

Place1  ул. "Цанко Церковски" No37  Category1   bar Bulgaria    Sofia   310-808-5243
Place 2 ул."Ген. Гурко" No 6    Category2   bar Bulgaria    Sofia   415-846-1688
Place 3 ул. "Гео Милев" No 18   Category3   bar Bulgaria    Sofia   720-318-9049

And this is the output

instead of ул. "Цанко Церковски" No37, for example

I get: . , .

It probably has something to do with the encoding of the CSV file, But Im not sure how can I view/change that and whether I should use Word or Open Office?

Also, may I change the way Java reads such files so even if they are in the wrong encoding, Java fixes it?

Answer 1

This is quite possibly the problem:

CSVReader reader = new CSVReader(new FileReader(filepath));

FileReader always uses the platform-default encoding. I prefer to use InputStreamReader wrapped around a FileInputStream , as then you can specify the encoding:

try (InputStream stream = new FileInputStream(filepath)) {
    CSVReader reader = new CSVReader(new InputStreamReader(stream, "UTF-8"));
    ...
}

Answer 2

您可以像这里一样显式设置编码

new CSVReader(new InputStreamReader(new FileInputStream(filePath), encoding));
