+ * punycode_strerror:
+ * @rc: an #Punycode_status return code.
+ *
+ * Convert a return code integer to a text string.  This string can be
+ * used to output a diagnostic message to the user.
+ *
+ * PUNYCODE_SUCCESS: Successful operation.  This value is guaranteed
+ *   to always be zero, the remaining ones are only guaranteed to hold
+ *   non-zero values, for logical comparison purposes.
+ * PUNYCODE_BAD_INPUT: Input is invalid.
+ * PUNYCODE_BIG_OUTPUT: Output would exceed the space provided.
+ * PUNYCODE_OVERFLOW: Input needs wider integers to process.
+ *
+ * Return value: Returns a pointer to a statically allocated string
+ * containing a description of the error with the return code @rc.
