<P>[Adopted at the February, 2019 meeting as part of paper P1041R4.]</P>

<P>The resolution of <A HREF="1802.html">issue 1802</A> clarified
that <TT>char16_t</TT> string literals can contain surrogate pairs, in
contrast to <TT>char16_t</TT> character literals.  However, there is
no explicit requirement that <TT>char16_t</TT> literals be encoded as
UTF-16, although that is explicitly stated for <TT>char16_t</TT>
character literals, so it's not clear what the value is required to be
in the surrogate-pair case.</P>

<P><B>Rationale (February, 2019)</B></P>

<P>The Standard is now clear on this point.</P>
