             Bug #: 12191
           Summary: StmtPrinter::VisitStringLiteral is broken for Unicode
                    string literals
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org

For example:

// Assertion failure:
static_assert(0, L"\xFFFFFFFF");
// Translated to u"\uD885\uDFFF", which isn't a valid string literal:
static_assert(0, u"\U000317FF");
// Translated to u8"\316\251", which is correct, but really ugly:
static_assert(0, u8"Ω");
