Summary
| Description |
English: Detailed scheme of the UTF-8 encoding. Includes bits numbering and exact position of every bit. This scheme doesn't contain any localized labels (suitable for international use). Warning: this describes an old "non-standard" extension to support code points using up to 31-bit, all encodable to at most 6 bytes (such extension is no longer valid since the publication of ISO/IEC 10646:2003, The Unicode Standard 4.0, and the current RFC 3629 in the IETF Standard Tracks, that are restricting valid code points to the first 17 planes using at most 21 bits, all encodable into at most 4 bytes with more restricted valid values). Old applications depending on the older definitions by ISO/IEC 106464-1 or older RFCs, and still needing such extension to encode more planes, must not label this usage with "UTF-8", but may use "FSS-UTF" (which also has a distinct ASN OID). Français : Schéma détaillé de l'encodage UTF-8. Inclut la numérotation des bits et la position exacte de chaque bit. Ce système ne contient pas d'étiquettes localisées (appropriées à un usage international).
Avertissement : ceci décrit une ancienne extension non standard pour supporter les points de code jusqu'à 31 bits, tous encodable sur 6 octets max (une telle extension n'est plus valide depuis la publication de ISO/IEC 10646:2003, Le standard Unicode 4.0, et la RFC 3629 actuelle dans IETF Standard Tracks, qui restreignent les points de code valides au 17 premiers plans utilisant au plus 21 bits, tous encodables sur 4 octets max avec plus de restrictions sur les valeurs valides). Les anciennes applications dépendant de des anciennes définitions de ISO/IEC 106464-1 ou de RFCs plus anciennes, et nécessitant une telle extension pour encoder plus de plans, ne doivent plus appeler cette utilisation "UTF-8", mais utiliser le terme "FSS-UTF" (qui a également un OID ASN distinct). Русский: Подробная схема кодирования UTF-8 с нумерацией бит и указанием конкретного местоположения каждого бита. В схему специально не были включены локализованные надписи, чтобы можно было использовать в любом языковом разделе Википедии. |
