В кластер входят документы, посвященные техническим аспектам применения и конвертации кодировок символов при передаче данных в веб-среде.
Общие признаки: стандарт UTF-8, кодировка Windows-1251, передача данных между клиентом и сервером, совместимость браузеров
Группа выше: Кодировки и Unicode
Смысл: The main idea is that regardless of the desired server encoding, AJAX requests via JavaScript effectively standardize on UTF-8 for character transmission. Developers should embrace this by using UTF-8 on the client side and performing encoding conversion (e.g., using iconv in PHP) on the server side to maintain compatibility with legacy encodings like windows-1251.
The text explains how to handle Cyrillic characters in AJAX by using UTF-8 encoding on the client side and converting it to other encodings on the server using PHP's iconv.
Смысл: The main idea is that web servers (Nginx/Apache) must use the exact string 'utf-8' (with a hyphen) to ensure correct character rendering and AJAX functionality in Internet Explorer, despite other browsers being lenient and databases like MySQL using 'utf8' without a hyphen.
Use 'utf-8' instead of 'utf8' in Nginx and Apache configurations to prevent character encoding issues and AJAX errors in Internet Explorer.
Смысл: The main idea is to demonstrate how bypassing the standard UTF-8 requirement in favor of Windows-1251 allows for a much more efficient custom Binary-to-Text encoding, enabling the packaging of large binary assets into a single HTML file with minimal overhead.
By using Windows-1251 encoding and a custom Base223* algorithm, the author successfully packed 168MB of animation data into one HTML file with only 2.3% size increase.
