Function std.encoding.codeUnits
Returns a foreachable struct which can bidirectionally iterate over all code units in a code point.
CodeUnits!E codeUnits(E)
(
dchar c
);
The input to this function MUST be a valid code point. This is enforced by the function's in-contract.
The type of the output cannot be deduced. Therefore, it is necessary to explicitly specify the encoding type in the template parameter.
Supersedes
This function supersedes std.utf.encode().
