UTF-16
Sign in to saveAlso known as 16-bit Unicode Transformation Format, Unicode Transformation Format – 16-bit, Unicode Transformation Format - 16-bit, UTF16, UTF_16
UTF-16 (16-bit Unicode Transformation Format) is a character encoding that supports all 1,112,064 valid code points of Unicode. The encoding is variable-length as code points are encoded with one or two code units. UTF-16 arose from an earlier obsolete fixed-width 16-bit encoding now known as UCS-2 (for 2-byte Universal Character Set), once it became clear that more than 216 (65,536) code points were needed, including most emoji and important CJK characters such as for personal and place names.

UTF-16 (16 bitars unicode transformationsformat) är inom datatekniken en längdvarierande teckenkodning som används för att representera Unicodetext som sekvenser av dubbel-oktetter (16-bitstal). Den är en utvidgning av UCS-2. UTF-16 är standardiserad inom Unicode och ISO/IEC 10646. Den är såtillvida kompatibel med UCS-2, att all UCS-2-data också är UTF-16-data. Vissa kodvärden har reserverats för att, i par, kunna referera till tecken vars kodpunkter är större än 65535 (U+FFFF), så kallade supplementära tecken. Ursprungligen planerades Unicode klara sig med 16 bitar och UCS-2 var Unicode utan transformation. Det finns dock så många kinesiska tecken om alla ovanliga räknas med, att fler bitar behövdes.[källa behövs]
