Makarand Hinge commented on CSV-227:
------------------------------------
Hi [~ggregory],
I reviewed and ran JiraCsv227Test locally.
The test passes and correctly verifies that Unicode values in the first column
are not unnecessarily quoted under QuoteMode.MINIMAL.
This appears to resolve the issue. Thank you for adding the test.
