================
Comment at: clang/lib/Basic/Diagnostic.cpp:838-858
+      if (UseUCN)
+        OutStream << "\\u"
+                  << llvm::format_hex_no_prefix(CodepointValue, /*Width=*/4,
+                                                /*Upper=*/false);
+      else
+        OutStream << "<U+"
+                  << llvm::format_hex_no_prefix(CodepointValue, /*Width=*/4,
----------------
The use UCN addition is probably not justified. we should consistent in how we print the value of non-printable code points.


================
Comment at: clang/lib/Sema/SemaDeclCXX.cpp:16836-16837
+          const char CharArr[] = {static_cast<char>(CharVal)};
+          pushEscapedString(StringRef(CharArr, sizeof(CharArr)), Str,
+                            /*UseUCN=*/true);
+        }
----------------
A  different way to do that would be to have a 'Escape Whitespaces' parameter on pushEscapedString that would also escape \t, \n, etc (I don't think we want to escape SPACE)
