It's quite relevant. For example, if you are writing unit tests for some
library dealing with wide strings (or UTF-16 strings), it's quite common
to write string literals in your tests, so you need to be aware of this
problem: What will work just fine with gcc might not work with Visual
Studio, and your unit test will succeed in one but not the other.

The solution offered elsewhere in this tread is the correct way to go,
ie. using the "\uXXXX" escape codes for such string literals, as they
will always be interpreted correctly by the compiler (even if the
readability of the source code suffers as a consequence).
