I'm not sure if this is a bug or wanted behavior:
auto x = to!string(cast(char)255);
That won't throw. But this will:
auto x = to!string(cast(char)255); // or try 128
auto z = toUTF8(x); // throws
I've had this example code translated from C:
foreach (y; 0 .. 16)
foreach (x; 0 .. 16)
{
auto buffer = to!string(cast(char)(16 * x + y));
auto result = buffer.toUTF16z; // call to utf16z for the winapi
}
Essentially the code builds a table of characters that it prints out. But it
doesn't seem to take into account invalid UTF8 code points.
This leads me to another question, how does one iterate through valid UTF code
points, starting from 0? Is there a Phobos function that does that?
