<div>I am not sure what you are asking. Most of the
u8"literals" I am seeing contain non-ASCII characters. Many
as literal characters, a bunch of \uhhhh, and a few
\U00hhhhhh.</div>

<p>Steve, I'm guessing the question you're trying to get at is,
would there be any behavioral difference if the u8 prefix was
simply dropped? I think this is equivalent to asking the
question, are the source files for these examples encoded as UTF-8
and is the compiler invoked such that the source encoding and
presumed execution encoding are both UTF-8 (always the case for
Clang, the default for gcc unless -finput-charset or
-fexec-charset is used, and not the case for MSVC unless /utf-8 is
used).</p></div><div bgcolor="#FFFFFF" text="#000000">
