   Yes, the topic name should follow the rule as follow:
   ```java
       // allowed characters for property, namespace, cluster and topic names are
       // alphanumeric (a-zA-Z_0-9) and these special chars -=:.
       // % is allowed as part of valid URL encoding
       public static final Pattern NAMED_ENTITY_PATTERN = Pattern.compile("^[-=:.\\w]*$");
   ```
   
   Pulsar hasn't a good topic name limit yet, but it is being added.
