    [ https://issues.apache.org/jira/browse/AVRO-2174?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16494604#comment-16494604 ] 

Michael A. Smith commented on AVRO-2174:
----------------------------------------

Linked to AVRO-1725, which describes some of the history. To summarize: it was discovered that in avro 1.7.7 in the _Java_ implementation, specifically, enum symbols were rejected if they weren't valid names. It was decided to make the spec match the Java behavior in 1.8.0.

> The Avro spec does not allow for spaces *' '*  in enums. However, Python Avro does not error out or reject enums with spaces in them.
> This is an example of a part of a schema which was accepted by the python package:
> {code}
> {
> "default": null,
> "type": [
> "null",
> {
> "symbols": [
> "top left",
> "top center",
> "top right",
> "center left",
> "center center",
> "center right",
> "bottom left",
> "bottom center",
> "bottom right"
> ],
> "type": "enum",
> "namespace": "",
> "name": "postion_enum"
> }
> {code}
>  
> The same schema, when read by the Java library errors out at *top left* as expected:
> {code}
> Caused by: org.shaded.apache.avro.SchemaParseException: Illegal character in: top left
>  at org.shaded.apache.avro.Schema.validateName(Schema.java:1151)
>  at org.shaded.apache.avro.Schema.access$200(Schema.java:81)
>  at org.shaded.apache.avro.Schema$EnumSchema.<init>(Schema.java:749)
>  at org.shaded.apache.avro.Schema.parse(Schema.java:1300)
>  at org.shaded.apache.avro.Schema.parse(Schema.java:1340)
>  at org.shaded.apache.avro.Schema.parse(Schema.java:1269)
>  at org.shaded.apache.avro.Schema$Parser.parse(Schema.java:1032)
>  at org.shaded.apache.avro.Schema$Parser.parse(Schema.java:1020)
> {code}
