The documentation page 
http://dlang.org/spec/lex.html

should say more about combination of hex strings and 'w'/'d' postfix. Do such
strings get transformed from UTF8? If yes, what happens with invalid ones? If
not, is there a way to write UTF8 in hex and have it transformed by the
compiler w/o any runtime cost?
