All above file is download, only Failed to set filetime.

Use old version on XP without this problem.

I expected the following

Use this：
https://sslsites.de/paehl.com/open_source/?CURL_7.71.0
and this：
https://skanthak.homepage.t-online.de/curl.html

build no this problem.

The setfiletime function uses CreateFileA. There were Unicode changes made to the curl tool recently and I suspect that may have something to do with it. Probably the filename is UTF-8 encoded now? @MarcelRaad

curl/src/tool_filetime.c

Lines 106 to 129 in 5a1fc8d

	hfile = CreateFileA(filename, FILE_WRITE_ATTRIBUTES,
	(FILE_SHARE_READ | FILE_SHARE_WRITE |
	FILE_SHARE_DELETE),
	NULL, OPEN_EXISTING, 0, NULL);
	if(hfile != INVALID_HANDLE_VALUE) {
	curl_off_t converted = ((curl_off_t)filetime * 10000000) +
	CURL_OFF_T_C(116444736000000000);
	FILETIME ft;
	ft.dwLowDateTime = (DWORD)(converted & 0xFFFFFFFF);
	ft.dwHighDateTime = (DWORD)(converted >> 32);
	if(!SetFileTime(hfile, NULL, &ft, &ft)) {
	fprintf(error_stream,
	"Failed to set filetime %" CURL_FORMAT_CURL_OFF_T
	" on outfile: SetFileTime failed: GetLastError %u\n",
	filetime, (unsigned int)GetLastError());
	}
	CloseHandle(hfile);
	}
	else {

Thanks for the report, and sorry for noticing it so late! Should be fixed with #5718.

Now I get:
