While reading the data from file inputstreamreader converts special characters into replacement character. For e.g. BleȬÁno is converted into Ble?Áno

My code is :

public String getUploadFileAsString() {
    try {
        final InputStream stream = file.getInputStream();
        final StringWriter writer = new StringWriter();
        IOUtils.copy(stream, writer, IrisHttpCommon.UTF8Charset);
        return writer.toString();
    } catch (final IOException e) {
        throw new IrisException("exception in getUploadFileAsString()", e);

I have tried IOUtils, CharStream, Scanner, BufferedReader, InputStreamReader but nothing solves the problem.

Charset charset = StandardCharsets.UTF_8;
try (BufferedReader br = Files.newBufferedReader(path, charset)) {
  return br.lines().collect(Collectors.joining());

Specyfing correct input Charset should solve your problem.
