You didn't mention what OS you are using, what version of libcurl you
have, or what resolver library it was configured to use, so it is
difficult to say exactly what would be causing your problem. However,
addresses in this form do work OK for me using c-ares under Linux:

$ strace -f ./curl -g http://[805B:2D9D:DC28::FC57:212.200.31.255]/ 2>&1
|grep 805b
connect(3, {sa_family=AF_INET6, sin6_port=htons(80), inet_pton(AF_INET6,
"805b:2d9d:dc28::fc57:d4c8:1fff", &sin6_addr), sin6_flowinfo=0,
sin6_scope_id=0}, 28) = -1 EINPROGRESS (Operation now in progress)
