-----------------------------
> [C++] Handle quoted field names during string schema parsing
> ------------------------------------------------------------
>
> Key: ORC-1047
> URL: https://issues.apache.org/jira/browse/ORC-1047
> Project: ORC
> Issue Type: Improvement
> Components: C++
> Affects Versions: 1.8.0
> Reporter: noirello
> Assignee: noirello
> Priority: Major
> Fix For: 1.8.0
>
>
> The current implementation of _Type::buildTypeFromString_ cannot handle
> string schemas with quoted field names. The following code will raise a logic
> error of "Unrecognized character.":
> {code:java}
> auto schema = Type::buildTypeFromString("struct<`quoted.field`:string>"); //
> Fails
> {code}
> Besides that, two other limitations have been encountered:
> * Cannot parse a string schema that only has a _timestamp with local time
> zone_ type in root.
> {code:java}
> Type::buildTypeFromString("timestamp with local time zone"); // Fails
> {code}
> * It allows to create struct types without setting a field name, which
> (based on the Java implementation) should not be a valid ORC schema.
> {code:java}
> Type::buildTypeFromString("struct<struct<bigint>>"); // Works
> {code}
