43 | * Macros Curl_convert_UTF8_to_tchar(), Curl_convert_tchar_to_UTF8() |

45 | * preprocessor conditional directives needed by code using these |
46 | * to differentiate UNICODE from non-UNICODE builds. |
47 | * |
48 | * When building with UNICODE defined, this two macros |
49 | * Curl_convert_UTF8_to_tchar() and Curl_convert_tchar_to_UTF8() |
50 | * return a pointer to a newly allocated memory area holding result. |
51 | * When the result is no longer needed, allocated memory is intended |
52 | * to be free'ed with Curl_unicodefree(). |
53 | * |
54 | * When building without UNICODE defined, this macros |
55 | * Curl_convert_UTF8_to_tchar() and Curl_convert_tchar_to_UTF8() |
56 | * return the pointer received as argument. Curl_unicodefree() does |
57 | * no actual free'ing of this pointer it is simply set to NULL. |
