In mobile telephony GSM 03.38 or 3GPP 23.038 is a character encoding used in GSM networks for SMS (Short Message Service), CB (Cell Broadcast) and USSD (Unstructured Supplementary Service Data). The 3GPP TS 23.038 standard (originally GSM recommendation 03.38) defines GSM 7-bit default alphabet which is mandatory for GSM handsets and network elements, but the character set is suitable only for English and a number of Western-European languages. Languages such as Chinese, Korean or Japanese must be transferred using the 16-bit UCS-2 character encoding. A limited number of languages, like Portuguese, Spanish, Turkish and a number of languages used in India written with a Brahmic scripts may use 7-bit encoding with national language shift table defined in 3GPP 23.038. For binary messages, 8-b

  • GSM 03.38 (nebo také 3GPP 23.038) je označení normy, která definuje znakovou sadu používanou službou krátkých textových zpráv (zkratka SMS z anglického Short message service) v mobilních telefonech GSM. Základní znaková sada definovaná touto normou se nazývá GSM 7 bit default alphabet. Znaková sada obsahuje 3 řídicí znaky: Line feed, Carriage return a Escape. Znak Escape se používá ke zpřístupnění znaků z tabulky Basic Character Set Extension – jeden znak za Escape se bere z této alternativní tabulky. Pomocí informačních prvků s hodnotami 0x24 a 0x25 (National language shift tables) v User Data Header lze změnit jednu nebo obě tabulky za národní tabulky pro různé jazyky. (cs)
  • Es gibt drei verschiedene Möglichkeiten, Texte und Daten in einer GSM-Kurznachricht mit einer maximalen Nutzdatenmenge von 1120 Bit zu kodieren: 7 Bit, 160 Zeichengemäß Standard GSM 03.38, ugs. GSM-Alphabet. Für SMS-Textnachrichten, bei denen ein begrenzter Zeichenvorrat zur Darstellung ausreichend ist. Der Text kann pro Nachricht bis zu 160 Zeichen enthalten (7 Bit/Zeichen × 160 Zeichen = 1.120 Bit). Jeweils 7 Bit werden als ein Zeichen interpretiert, was den Vorrat an darstellbaren Zeichen grundsätzlich auf 128 beschränkt. Diese 128 Zeichen sind im 7-Bit-Basiszeichensatz festgelegt. Es existieren mehrere Mechanismen, mit denen der Vorrat an darstellbaren Zeichen erweitert werden kann: * Escape: Durch das Escape-Zeichen (ESC, 0x1B) wird für die Anzeige des direkt folgenden Zeichens einma (de)
