Ah, indeed. nginx doesn't allow anything but [A-Za-z0-9_] in
variable names, and it's basically impossible to extract cookie
with other chars in it's name via $cookie_* variables.

The only solution I see is to parse cookie header manually, e.g.
by something like this:

server {
...

proxy_cache_key "$host$request_uri $xx";

set $xx "";
if ($http_cookie ~ "(^|[;,])jetbrains\.charisma\.main\.security\.PRINCIPAL=([^;,]+)($|[;,])") {
set $xx $2;
}

...
}
