A standard method of directly encoding Unicode using two bytes for every character.
Note: SNOMED CT release files do not use UTF-16. However, the UTF-8 representation used in release files can be converted to UTF-16.
A standard character set, which represents most of the characters used in the world using a 16-bit encoding.
Note: The Unicode character set can be encoded using either UTF-16 or UTF-8. UTF-16 uses two bytes for every character. UTF-8 is able to store the most commonly used characters in western alphabets using a single byte, but it requires two bytes to encode accented characters and three bytes to encode symbols used in many non-European scripts.
A datatype representing a Universally Unique Identifier encoded as a 128-bit integer.
Note: In SNOMED CT release files UUIDs are represented as a string following the standard canonical form. In this string form a UUID is represented by 32 hexadecimal digits, displayed in five groups separated by hyphens, in the form 8-4-4-4-12 for a total of 36 characters (32 digits and four hyphens).
Example: ac527bed-9c70-4aad-8fc9-015828b148d9
A standard method of encoding Unicode characters in a way optimized for the ASCII character set. UTF-8 is described in Unicode UTF-8 encoding.
Note: This encoding is used for release file fields of data type "String".
