Java. IO. Encoding errors when reading a file

I have this method that reads the file:

        private String fileContent = "";

        void writeFile(String path) {
            try (FileInputStream input = new FileInputStream(path)) {
                int stream = input.read();
                while (stream != -1) {
                    this.fileContent = String.format("%s%s", this.fileContent, ((char)stream));
                    stream = input.read();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

When I read the English alphabet from the file, everything is OK. But when I try to count the Cyrillic alphabet, I get hieroglyphs. Although in the file from which I read the UTF-8 encoding and in the development environment I have UTF-8 is. Can you tell me how to fix it?

I decided like this. Maybe it will be useful for someone else. Directly from the file to the required encoding.

    private String fileContent = "";
    private void writeFile() {
        try (BufferedReader br = new BufferedReader(
                new InputStreamReader(
                        new FileInputStream(this.path), "UTF-8"))) {
            String sub;
            while ((sub = br.readLine()) != null) {
                this.fileContent = String.format("%s%s\n", this.fileContent, sub);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
