Currently, the names of nginx variables can be composed from
upper and lower English letters, digits and underscores. The
dash and dot characters are thus invalid.

Without patching the code, you should be able to log the entire
value of the "Cookie" request header field with the $http_cookie
variable. It can also be useful if you have cookies whose names
only differ in case as $cookie_<name> doesn't differentiate
between upper and lower case:

http {
server {
location / {
return 200 'http_cookie=$http_cookie cookie_a=$cookie_a cookie_A=$cookie_A\n';
}
}
}

$ curl -b 'a=a;A=A' http://localhost:8000/test
http_cookie=a=a;A=A cookie_a=a cookie_A=a
