+Subject: [PATCH] emitterutils: Explicitly include <cstdint>
+
+GCC 15 will no longer include it by default, resulting in build
+failures in projects that do not explicitly include it.
+
+Error:
+src/emitterutils.cpp:221:11: error: 'uint16_t' was not declared in this scope
+  221 | std::pair<uint16_t, uint16_t> EncodeUTF16SurrogatePair(int codePoint) {
+      |           ^~~~~~~~
+src/emitterutils.cpp:13:1: note: 'uint16_t' is defined in header '<cstdint>';
+this is probably fixable by adding '#include <cstdint>'
+   12 | #include "yaml-cpp/null.h"
+  +++ |+#include <cstdint>
+   13 | #include "yaml-cpp/ostream_wrapper.h"
+
+Tests pass.
+
+Closes: #1307
