+## JSON in C++: escaping and serialization
+
+Using JSON escaping as a context we will explore:
+* UTF-8, Unicode, and minimal implementation to support them (a.k.a. what you need to know but maybe don't);
+* how to account for different implementations using `contexpr` (considering performance);
+
+Looking at JSON serialization/stringification we'll touch:
+* ways to iterate over elements in JSON document with account for recursion;
+* nuance of serializing floating point numbers;
+* error reporting and nuances of exception types (in the context of serializing strings);
+* serializing elements of unordered map in sorted order.
+
+And a bit more.
