+Subject: [PATCH] Do not rely on std::char_traits template from stdlib
+
+standard never required the base template for
+char_traits to any type but it was given for
+convenience purposes. Nowadays, at least in LLVM's
+libcxx version 19+ it got removed [1].
+
+GCC might follow the same path at some point so
+porting it away from char_traits might be a good
+idea.
+
+The fix is applied to FreeBSD [2] [3]
+
+Reported issue [4]
