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