+ * to differentiate UNICODE from non-UNICODE builds.
+ *
+ * When building with UNICODE defined, this two macros
+ * Curl_convert_UTF8_to_tchar() and Curl_convert_tchar_to_UTF8()
+ * return a pointer to a newly allocated memory area holding result.
+ * When the result is no longer needed, allocated memory is intended
+ * to be free'ed with Curl_unicodefree().
+ *
+ * When building without UNICODE defined, this macros
+ * Curl_convert_UTF8_to_tchar() and Curl_convert_tchar_to_UTF8()
+ * return the pointer received as argument. Curl_unicodefree() does
+ * no actual free'ing of this pointer it is simply set to NULL.
