Record Splitter (Delimited) - With pipe | value delimiter the records splits with each letter. With [|] and \\| inserted in BQ, then same letters splits.

BQsource->Record Splitter->GCSsink, provide | pipe delimiter in delimiter field in record splitter plugin, having record values in BQ table the output generated is letter split.

Steps to reproduce:

1. Launch the latest CDAP (6.8.0)

2. Open BigQuery source, record splitter plugin and GCS sink, now establish the connection from source to transform to sink (BQ source->Record Splitter->GCS sink). Fill the properties, provide | pipe delimiter value and click on validate. Already inserted the data in BQ table with | values.

3. Inserted the data with double slash in BQ table as below.

4. insert into `cdf-athena.test_automation.delimiterslashtest`(user, item, action) values ('pipe5|pipe6|pipe7|pipe8|pipe9','donut','buy');

5. Now click on preview of pipeline.

6. And deploy the pipeline, record splits with each letter.

7. Also when value inserted with [|] \\| in BQ table like below,

8. insert into `cdf-athena.test_automation.Delimited`(user, item, action) values ('pipe5\\|pipe6\\|pipe7\\|pipe8\\|pipe9','donut','buy');

   then output value generated as letter split.

9. Attached the screenshots reference.

Expected: | pipe delimiter splits record with each letter in output.
Actual: Only value before pipe | delimiter should be splitted.
