[AdminAPI] Kafka createTopics returns nil error even if it can't create topic.

Description

Hi,

I am trying to create a kafkatopic with this config using AdminAPI createTopics function.

{
"name": "user:created",
"numberOfPartitions": 3,
"replicationFactor" : 2
}

The topic is not getting created since kafka doesn't support anything other than "[a-zA-Z0-9\\._\\-]" but the error returned from the createTopics function shouldn't be nil.

Has anyone faced similar issue before?

I'm following the example at https://github.com/confluentinc/confluent-kafka-go/blob/master/examples/admin_create_topic/admin_create_topic.go

How to reproduce

In the latest version, this doesn't seem to be happening anymore, using the same example

$ ./admin_create_topic localhost:9092 'user:bin' 1 1
user:bin (Topic name is invalid: 'user:bin' contains one or more characters other than ASCII alphanumerics, '.', '_' and '-')```

Is this now solved for you, too?
