encode(_:into:)
Encodes a Unicode scalar as a series of code units by calling the given closure on each code unit.
static func encode(_ input: Unicode.Scalar, into processCodeUnit: (Unicode.UTF16.CodeUnit) -> Void)
Parameters
- input
The Unicode scalar value to encode.
- processCodeUnit
A closure that processes one code unit argument at a time.
For example, the musical fermata symbol (βπβ) is a single Unicode scalar value (\u{1D110}
) but requires two code units for its UTF-16 representation. The following code encodes a fermata in UTF-16:
var codeUnits: [UTF16.CodeUnit] = []
UTF16.encode("π", into: { codeUnits.append($0) })
print(codeUnits)
// Prints "[55348, 56592]"
