Escaping special chars when exporting result sets

Hi all!

We use Solr 4.10.3 and have configured an /export SearchHandler in 
addition to the default SearchHandler /select.

<requestHandler name="/export" class="solr.SearchHandler">
   <lst name="invariants">
     <str name="rq">{!xport}</str>
     <str name="wt">xsort</str>
     <str name="distrib">false</str>
     <str name="fl">username,description</str>
    </lst>
   <arr name="components">
     <str>query</str>
   </arr>
</requestHandler>

The handler follows the example from section "Exporting Result Sets" of 
the user guide.

The description field may contain line breaks (\n) and quotation marks (").

When using the /select handler those characters are properly escaped. 
E.g. we get following value in the response:

"description":"Lorem ipsum\n\ndolor sit amet. \"hello\" world \" test....",

BUT when using the /export handler those characters are NOT escaped. We get:

"description":"Lorem ipsum

dolor sit amet. "hello" world " test...."

The latter is not valid JSON in our understanding.

What are we doing wrong? How can we get properly escaped JSON?

Thanks in advance!

Best regards,
Angelo Veltens

This should be considered a bug in the /export handler. Please create a
jira ticket for this.

Thanks
