Reworded. Is that more clear?

UCNs were in '98. '11 relaxed the restriction that a UCN could not name a member of the basic execution character set or a control character to only apply outside of string and character literals. The tests pass with clang 3.6 (the oldest I have readily available) in '03 mode, and gcc-4.9 in '11 mode. GCC won't compile the test in '03 mode due to the use of default template arguments in `<memory>` and `<string>`.
