Question

I have a multipart format text file. i am going threw the file looking for start of content and from then on writing the content to another file until i hit end of content.

FileInputStream in = new FileInputStream(getContentPath());

InputStreamReader sr = new InputStreamReader(in, "UTF-8");

BufferedReader buffreader = new BufferedReader(sr);

String lineStr;

while ((lineStr = buffreader.readLine()) != null) {

    if (lineStr == "") {
    FileOutputStream fos = new FileOutputStream("", true);
    OutputStreamWriter writer = new OutputStreamWriter(fos, "UTF-8");

    BufferedWriter fbw = new BufferedWriter(writer);
    fbw.write(lineStr);
    fbw.newLine();
    fbw.flush();
    fbw.close();
    }
}

The problem i am getting is the resulting files encoding is all messed up. The input is utf8.

Original in multipart format

Answer 1

Found problem the input charset was not utf8 it is iso-8859-1 http default.

Used CharsetDecoder to make sure i read/saved string as iso-8859-1.
