Кодировка cp866

| Описание кодировки |

Альтернативная кодировка, или cp866 ("code page 866"), долгое время оставалась основной кодировкой русских букв, используемой при работе с персональным компьютером, пока бурное развитие Интернет не потеснило ее позиции в сторону "сетевых" кодировок, таких как Windows-1251 или koi8-r. Тем не менее, до сих пор эта кодировка находит свое применение и, судя по всему, будет использоваться еще очень долгое время.

Краткое имя кодировки: | alt
Официальное имя кодировки: | cp866
Синонимы, принятые в FLUIdS: | cp-866, dos, ibm866
Стандарты: | Microsoft code page 866

Строго говоря, этому стандарту отвечает следующая таблица символов:

Легко видеть, что она несколько отличается от принятой в FLUIdS (в последней строчке). Это отличие непринципиально (если дело не касается украинского или беларусского языков), зато дает возможность однозначного, взаимообратного соответствия наборов символов для кодировок alt, koi и sco.
