+ * curlx_convert_UTF8_to_tchar() and curlx_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 curlx_unicodefree().
+ *
+ * When building without UNICODE defined, this macros
+ * curlx_convert_UTF8_to_tchar() and curlx_convert_tchar_to_UTF8()
+ * return the pointer received as argument. curlx_unicodefree() does
+ * no actual free'ing of this pointer it is simply set to NULL.
