The export fails with following errors recorded in the log:

"ExportManagerImpl Export is failed, cause: A quoted literal may not contain any control characters - controls must be escaped using \uHHHH; at Input Source: "MarcInput", Line: 1, Column: 110, Member Name: 007"

2021-08-06T14:59:01,896 ERROR [vert.x-eventloop-thread-1] ExportManagerImpl Export is failed, cause: A quoted literal may not contain any control characters - controls must be escaped using \uHHHH; at Input Source: "MarcInput", Line: 1, Column: 110, Member Name: 008

This is an example of another error that halts data export.

2021-09-13T20:15:30,595 ERROR [vert.x-eventloop-thread-1] ExportManagerImpl Export is failed, cause: A string value cannot contain data after its closing quote (this is most likely caused by a missing comma between members); at Input Source: "MarcInput", Line: 1, Column: 2639, Member Name: ind1

Steps to Reproduce:

1. Manually update SRS record in the database so that it  contains three control characters (bell, character 7) – one in 006, one in 007, and one in 008. You can also a backslash to those fields just in case there are interpretation issues with those (this will contain the data similar to the attached  test.mrc file. You can also add some text after a closing double quote to check another error.
2. Export several records, including the one manually modified in prior step.

Expected Results:

• The error is handled gracefully
• The status of the export is Completed with errors. 
• Not affected records are successfully exported.
• The information about the affected record is  added to the user error log using the standard entry :

  <dateandtime> ERROR A quoted literal may not contain any control character. Field name <affected fields>
  {
  "Instance UUID": "<affected record uuid>"
  "Instance HRID": "<affected record hrid>"
  "Instance Title": "<title>"
  "Inventory record link": <link to the record>
  }
  

Actual Results:

Export job fails.  Error log contains only Generic error information.
