Issue with accent Letters in Spanish with BufferedWriter & CsvWriter

[KedemBarak]

Facing an issue with accent Letters in Spanish with BufferedWriter & CsvWriter:
for some reason when I try to write some letters they are being changed for unclear reason
this string:
SİSTA+UNİVERSAL+SİLİKON+&pace&ar

converted into:
SÄ°STA+UNÄ°VERSAL+SÄ°LÄ°KON+&pace&ar
I believe That is not the expected behavior.

The İ is converted into Ä°

As you can see I set the encoding in the example.

public static void main(String[] args) throws IOException {
	Writer writer = new FileWriterWithEncoding("c:/temp/xzyz.csv", "UTF8");
	String arr[] = {"SİSTA+UNİVERSAL+SİLİKON+&pace&ar"};
	BufferedWriter bufferedWriter = new BufferedWriter(writer);
	CSVWriter csvWriter = new CSVWriter(bufferedWriter);
	csvWriter.writeNext(arr);
	csvWriter.close();
}

I used Office Excell to open the generated file.

This is the result
