В UTF-8 запрещено использовать кодовые последовательности не минимальной длины, например юникоды с номером до 127 требуется кодировать именно в один байт, а не в 2,3 и так далее. А если так всё-таки сделать, полученная фигня называется оверлонгом (overlong). Вот этот код их как раз и создаёт. Но только из ASCII символов и расширяя их только до двух байт. Написание более универсального варианта, если вдруг кому-то надо оставляем как упражнение для читателя.

Что интересно, некоторые текстовые редакторы, если в них открыть файл, сделанный этой программой, увидят обычный текст.
