| * to differentiate UNICODE from non-UNICODE builds. |
| * |
| * When building with UNICODE defined, these two macros |
| * 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. |
