Typealiases

Type members

• init()

  Creates an instance of the UTF-16 codec.

• static var encodedReplacementCharacter: Unicode.UTF16.EncodedScalar
• static func decode(Unicode.UTF16.EncodedScalar) -> Unicode.Scalar
• static func encode(Unicode.Scalar) -> Unicode.UTF16.EncodedScalar?
• static func encode(Unicode.Scalar, into: (Unicode.UTF16.CodeUnit) -> Void)

  Encodes a Unicode scalar as a series of code units by calling the given closure on each code unit.

• static func isASCII(Unicode.UTF16.CodeUnit) -> Bool

  Returns whether the given code unit represents an ASCII scalar

• static func isLeadSurrogate(Unicode.UTF16.CodeUnit) -> Bool

  Returns a Boolean value indicating whether the specified code unit is a high-surrogate code unit.

• static func isSurrogate(Unicode.UTF16.CodeUnit) -> Bool

  Returns a Boolean value indicating whether the specified code unit is a high or low surrogate code unit.

• static func isTrailSurrogate(Unicode.UTF16.CodeUnit) -> Bool

  Returns a Boolean value indicating whether the specified code unit is a low-surrogate code unit.

• static func leadSurrogate(Unicode.Scalar) -> UTF16.CodeUnit

  Returns the high-surrogate code unit of the surrogate pair representing the specified Unicode scalar.

• static func trailSurrogate(Unicode.Scalar) -> UTF16.CodeUnit

  Returns the low-surrogate code unit of the surrogate pair representing the specified Unicode scalar.

• static func transcode<FromEncoding>(FromEncoding.EncodedScalar, from: FromEncoding.Type) -> Unicode.UTF16.EncodedScalar?
• static func transcodedLength<Input, Encoding>(of: Input, decodedAs: Encoding.Type, repairingIllFormedSequences: Bool) -> (count: Int, isASCII: Bool)?

  Returns the number of UTF-16 code units required for the given code unit sequence when transcoded to UTF-16, and a Boolean value indicating whether the sequence was found to contain only ASCII characters.

• static func width(Unicode.Scalar) -> Int

  Returns the number of code units required to encode the given Unicode scalar.

Instance members

• func decode<I>(inout I) -> UnicodeDecodingResult

  Starts or continues decoding a UTF-16 sequence.
