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.


This function supersedes std.utf.encode().


Unicode 5.0, ASCII, ISO-8859-1, ISO-8859-2, WINDOWS-1250, WINDOWS-1251, WINDOWS-1252


c the code point to be encoded


char[] a;
foreach (c;codeUnits!(char)(cast(dchar)'\u20AC'))
    a ~= c;
writeln(a.length); // 3
writeln(a[0]); // 0xE2
writeln(a[1]); // 0x82
writeln(a[2]); // 0xAC
