Another possibility would be to compute and store ASCIIness of values while parsing CSV (ideally this should not cost anything CPU-wise). Then we can reuse that information to skip UTF8 validation for most values. Edit: actually, a quick attempt shows a significant decrease in CSV parsing speed. Too bad. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
