>                 Key: AVRO-2659
>                 URL: https://issues.apache.org/jira/browse/AVRO-2659
>             Project: Apache Avro
>          Issue Type: Bug
>          Components: java
>            Reporter: Ryan Skraba
>            Priority: Minor
>
> The Java implementation will parse a schema with an obviously bad name:
> {code:json}
> { "type":"record",
>   "name":"org.9apache.äv rö.🚎.$!#!@%$.Sïmplé۵",
>   "fields": [
>     {"name":"id", "type": "int"}
>   ]
> }
> {code}
> For Java: 
> * no rules are applied to the namespace part of a full name, and
> * the {{isLetterOrDigit}} methods in Character accept accented or multibyte 
> letters and digits
> * _(ambiguous)_ when a full name is specified, the namespace attribute is 
> entirely ignored.  Should it be an error if it contains a bad namespace?
> We should be applying the rules to all of the dot-delimited parts of a full 
> name and namespace (unless ignored).
