Christophe Le Saec commented on AVRO-3532:
------------------------------------------
About
[discussion|https://lists.apache.org/thread/8q666sll1hkh7hq7kbdthlv2dd9dfnr8],
i would have same opinion as Nilesh, lot of data sources like GCP storage he
mentioned but also relational database, json file format ...
Transport data format like [Apache
Arrow|https://arrow.apache.org/docs/format/Columnar.html#struct-layout]
({_}Each field must have a UTF8-encoded name{_}) or Amazon ion, ({_}that accept
every json{_}) also accept name, and it competes directly with Avro.
So, i think it could be great to develop Avro to align it (but, i understand
this would be a big work).

> Key: AVRO-3532
> URL: https://issues.apache.org/jira/browse/AVRO-3532
> Project: Apache Avro
> Issue Type: Wish
> Reporter: Christophe Le Saec
> Priority: Major
>
> Description of [naming rule on
> documentation|https://avro.apache.org/docs/current/spec.html#names] is
> {noformat}
> - start with [A-Za-z_]
> - subsequently contain only [A-Za-z0-9_]
> {noformat}
> But [java
> code|https://github.com/apache/avro/blob/master/lang/java/avro/src/main/java/org/apache/avro/Schema.java#L1578]
> use Character.isLetter method
> {code:java}
> char first = name.charAt(0);
> if (!(Character.isLetter(first) || first == '_'))
> throw new SchemaParseException("Illegal initial character: " + name);
> for (int i = 1; i < length; i++) {
> char c = name.charAt(i);
> if (!(Character.isLetterOrDigit(c) || c == '_'))
> throw new SchemaParseException("Illegal character in: " + name);
> }
> return name;
> {code}
> This method accept accent éùàçË ... and also chinese character (我) ...
> So, the aim of this ticket is to see if we can update the documentation, if
> other implementations (rust, C# ...) are also compatible with ?
