I have a feature request / request for help.

The feature:
When you enqueue a call, an interceptor can throw an Exception when trying to create a request, I can't find a way to catch this exception. This only seems possible in synchronous calls.

The reason why I need it:
Right now it seems like the BridgeInterceptor is gathering cookies from my WebView and forwarding these when needed. However, some websites set special characters in their cookies, like ó.
When these cookies are added to a new request, Headers.java throws an IllegalArgumentException which crashes the app.

I'm happy to help and send a PR if you can send me some pointers!
