Thank you, I will use requests.
Function _decodeContent() in curl.d consists:

if (encoding == "UTF-8") return cast(char[])(content);
auto scheme = EncodingScheme.create(encoding);
enforce!CurlException(scheme !is null, format("Unknown encoding 
'%s'", encoding));

Encoding name (in std.encoding) is transferred to the lower case 
and matches are checked among the supported encoding names. There 
is "utf-8", but there is no "utf8" (without the hyphen).
