[Haskell-cafe] Strange encoding issue with Text and Servant

[Jan von Löwenstein]

Oh, it happens with servant on the client side.

I use a swagger-codegen generated servant based client to access kubernetes.
Calling
https://github.com/soundcloud/haskell-kubernetes/blob/master/lib/Kubernetes/Api/ApivApi.hs#L475
 works
Calling
https://github.com/soundcloud/haskell-kubernetes/blob/master/lib/Kubernetes/Api/ApivApi.hs#L473
 doesn't.

>From what I see the `QueryParam "labelSelector" Text` is the same in both.

Logging the value gives the literal `=` as expected. Logging the (http-client)
requests shows the difference.

Best
