title: Azure table storage names - invalid characters
body: <p>I have the following table names in Azure table storage. Table names are generated automatically in my application and then created using table.CreateIfNotExists(tableName). Some work and some don't. When I dig into the error the extended error information tells me that the resource name contains invalid characters - however I am at a loss to work out what is invalid in the failing names - can anyone spot this?</p>
