It could me off guard just recently. E.g. git uses two strings separated by nul
in it's object format, and when I've tried to print out the contents as a
char[] using writeln it would only print out a small portion of it, even though
printing it as a byte[] would print much more.

Anyway this *is* a bug. We can't have it both ways:
writeln("bla\0bla");  // bla
writefln("%s", "bla\0bla");  // bla[NUL]bla
