* 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.
