You can do that -- as I said in my link, that requires that the
compiler emits UTF-8 as the execution charset for that literal. gcc
simply leaves the source bytes untrasformed if you don't pass the
various -fexec-charset options, so all it's required is that your
source code is encoded using UTF8-8. (I don't have any clue about
MSVC).

Again: stop using fromAscii, tr, etc.; use the equivalents that take
UTF-8 (fromUtf8, trUtf8, etc.).
