As I wrote my own encoding/decoding functions for Unicode characters I found
out that certain Unicode codepoints are not allowed to be encoded as UTF-8
sequences. I'm quoting from here:
http://www.cl.cam.ac.uk/~mgk25/unicode.html

"Also note that the code positions U+D800 to U+DFFF (UTF-16 surrogates) as well
as U+FFFE and U+FFFF must not occur in normal UTF-8 or UCS-4 data. UTF-8
decoders should treat them like malformed or overlong sequences for safety
reasons."

So the behaviour of the compiler is actually correct, and Phobos has a bug.
