Hello, Pulsar community: When creating a subscription, pulsar does not verify the name of the subscription, so the subscription name may contain some invisible characters in the created subscription. If the subscription name contains some invisible characters, when we delete the subscription by pulsar-admin, an error will be reported: Subscription not found.
We have two ways to solve the problem: 1. Check whether the subscription name contains invisible characters, if it does, throw an exception and fail to create the subscription; 2. Add a subscription name naming rule, for example: can only contain these characters "a-zA-Z_0-9" or "-=:.%" What do you think, leave your opinion :) Thanks LinChen
