Chapter 3, Lesson 2: Encoding, decoding.

When is manual control of encoding required:

• When interoperating with legacy/UNIX sys.
• r/w files in other languages.
• ASCII - 0-127 - 7-bit byte.
• for languagues other than English - 128-255 - 8-bit byte.
• code pages - ASCII for 0-127, and language specific values for 128-255.
• code page - a list of character codes (code points) in a certain order.
• code pages - support specific languages.
• Windows code pages - 256 code points + zero-based.
• Unicode - a massive code page with 10000+ characters
• stds for encoding Unicode - UTF-16, UTF-8,...
• overloaded Stream constructor - new StreamWriter("abc.txt", false, Encoding.Unicode);
