+/* The idea of the writer is basically symmetrical of the reader. While the
+ * reader emits various calls to your code, the writer takes basically the
+ * same calls and emit json out of it. It doesn't try to make any check on
+ * the order of the calls you do on it. Meaning you can theorically force
+ * it to generate invalid json.
+ *
+ * Also, unlike the reader, the writer expects UTF-8 encoded input strings.
+ * These strings will be UTF-8 validated, and any invalid character will
+ * cut the conversion short, before any invalid UTF-8 sequence, thus forming
+ * a valid UTF-8 string overall.
