If std.utf.toUTF8(dchar[]) is given bad input it sometimes seg-v's. DMD also 
seg-v's if the same input undergoes a dchar[] -> char[] translation at compile

Are you sure that toUTF8(char[]) segfaulted? The only case I see would
be elements with values above 0x10FFFF, though you should file a bug for
that case because Phobos uses "assert(0)" instead of "throw ...".

That may well have been the case, I was dealing with UTF convention code 
what I started seeing the error. What I would rely like to see is a 
cantFailToUTF8 function that will give you something no matter what it 
is given. It would be handy for debug output.
