InputStreamReader..............................................................................
  - InputStream: class that reads binary data in the form of bytes from a source.
  - InputStreamReader:  It reads bytes using the given InputStream and then converts them into chars
			based on a certain Charset (UTF-8, UTF-16).
  - has a read() method that reads a single character (bytes --> characters)

remember:
	InputStreamReader.read() != InputStream.read()

1. InputStreamReader reader = new InputStreamReader(new FileInputStream(filePath), StandardCharsets.UTF_8)
