[PATCH] D21712: [libcxx] [test] Avoid narrowing conversions in quoted.pass.cpp.

Avoid narrowing conversions in quoted.pass.cpp.

According to the Standard, when char has a signed range and wchar_t has an unsigned range, brace-init has to reject the potentially narrowing conversion.

Fixes MSVC error C2397 "conversion from 'char' to 'wchar_t' requires a narrowing conversion".
